I have been reading several threads about wheel and tire fitment problems in the 3rd gen section, and now I am worried my wheels/tires are not going to fit. My plan is to swap over my 18x8 +35 wheels onto my third gen. The tires are 235/40's...I have read so many threads about peoples tires rubbing in the rear. Am I going to have this problem? The car will be lowered on ST springs as well. Let me know what you guys think or know. Thanks.

 

Ya ...you're good to go...

I'm thinking those will fit. I'm running 16x7.5 +38mm on 225/50, your wheels will probably be a little more flush than mine if I am thinking about it right. I know that a 300zx wheel will rub in the rear without a spacer and they are +45 offset so I'm thinking yours will clear.

 

cool. What is the most offset anyone is running in the rears with an 8" wide wheel and not rubbing with no major fender processing? I am asking because I may use a spacer in the rear if I can get away with it.

Also what is the offset on the stock 92 SE wheels?

 

38mm iirc on the se stockers..

35mm is optimum for these cars

 

er... most offset = closer to body.. are you wanting to push these out toward the fender? if so that's 'least offset'. i rubbed the fender a little bit with 7" and 22mm offset... 8" +35mm will sit at exactly the same outer position as what i had... BUT... my tires stick out past the rim.. if you stretch-mount the same width tire I have onto a 8" +35mm wheel, there would be no rubbing, because the tire would be narrower than the rim, which gives you more fender clearance.

and uh, stock 92SE is 15x6.5 +35mm but remember offset is measured from the center so adding 1.5" of width will change clearance inside and out. stock wheel info on pg GI-18 in the FSM

 

u r good to go with those specs...

 

yes, I do mean the least offset. I want to know what the lowest offset I can run on an 8" wide wheel and 235/40 tire with out major fender processing or lots of negative camber.

 

I'm running 17x8 +25 with a minor fender roll on one side. 245/40/17 tires.

If mine will fit, your 18x8+35 with 235/40 will fit.

 

jeebus... I don't get how you guys do it. 17x7 +22 rubbed like a **** for me over bumps and around corners, at STOCK ride height (SE springs, not-so-great rear struts).... and you're lowered with 10mm LESS fender clearance than I had. and you say you only rolled one side and not the other?

 

Rolling the fender lip in is like at least 10-15mm added to clearance cape...

not sure about the one side thing though.

 

well he said 'minor' roll so i figured it only added a little bit. i liked my old wheels for being 7-spokes but couldn't deal with the tire rub. the ones i have now look nice too... but they are boat anchors.

 

wat tire size r u running cape?

 

225 50 17. if i had 205 55 17 stretched onto 7" i probably would not have been rubbing. or likewise, my 225 50 17 stretched onto an 8" rim with the same outside-position as my old rims... probably wouldn't rub there either. but my section width is wider than my rim width... so the tire sticks out past the edge of the rim... which reduces clearance. even a 7.5" rim with 28mm offset probably would have worked for me on my current tires... and 8" with 35mm offset would have worked for sure.

 

wat i can think ritenow is that u may run 225/40/17 and put like 6mm spacer on the rear? its gonna decrease the tire height but width going to be increased atleast wont hit ur fender?

u can see the exact difference on this web

.........

on my old rims.... if i was already too close to the fender... why would i run a spacer? that would make the problem worse. I should have gotten 205 55's and just had them stretch onto my 17x7's.. cuz a stretched tire is narrower towards the tread and wider as it nears the rim. basically, if the rim is inside the fender then the tire will always be. on normal mounting, the tire sits a little outside the rim. obviously there are risks in stretching tires... go too far and the tire can unmount or blow a bead. not good. but 225 on an 8" rim is just fine.

stretch vs normal:

normal -> http://us1.webpublications.com.au/st.../1348_51lo.jpg

and there's no way in HELL that i'm going to go buy new tires to get undersize ones. i spent $130 each on these damn Toyos, which was too much as it is. I deliberately chose oversized tires rather than undersized, for MPG purposes. keeping up with traffic takes less RPM on bigger tires. my speedo will read a bit slow, but that's fine with me. besides your recommendation of 225 40 17 is like what you would put on a corolla... 24.1". stock for us is 25.5" and mine are 25.9". so... your recommendation would be for a tire 7% smaller than what i have now. that's a big difference. not to mention they'd look completely stupid on stock ride height. greeny runs 225/50/16 (24.9") and even those look somewhat small to me.. and he has a 1.6" drop.

Besides i put a different set of wheels on (with a 38mm offset) and just had my tires remounted onto them. No more rubbing now. See?

 

i thought u were dropping ur car in near future? thats why i told u to use that size....and for the info i was jus telling u to decrease aspect ratio so u would have better handling but ofcourse tire's height gonna get smaller but at the same time its gonna get wider too....low aspect ratio better corners....ok lets take it this way 16"rim and 20"rim, 16" has 245mm and 20" has 295mm WIDTH, and aspect ratio on 16" is 75 and on 20" it is 45 and guess wat? they both have the same diameter 30.4 inches but 20" inch rim would have WAY better handling than 16"rim.....well this is me i like to corner alot....and i can sacrifice a lil bit fuel economy plus i wont really have any probs wen i will lower my car....again its me..everyone have their own taste...

and ur car looks good man

 

OT I know, but there is no absolute guarantee of improved fuel economy with over-sized (rolling circumference) tires.

Most (?) cars will perform worse (ito mpg) with over-sized tires to achieve the same performance under the same conditions because it requires more torque to make the wheels turn - something that very few cars can manage without increasing throttle input.

Your revs will drop for any given speed with tires having a bigger rolling circumference but that is not a direct indication of improved economy given the need for the same performance on the vehicle - you will often find with autos that they demonstrate this by insisting on kicking down sooner because of the increased throttle input

 

I'll post a few pics for reference. My old wheels:

16x8 +50 w/ 32mm adapter, +18 effective offset. These would rub on big bumps, no fender roll:



Not exactly the same angle, but 20mm adapter, 30 offset, just about perfect IMO.





Friends don't let friends run huge offset...

 

Holy crap these pictures are 5 year old, but +30 all around w/ 225/50-16

 

Thanks for the pictures. It does not look like you are lowered at all...is that the case? When you were running +30 on an 8" wide wheel did you ever rub? Big bumps? Wheel at full lock? By looking at the pictures I am thinking I may run a ~5mm spacer in the rear.

 

i see where you're coming from, but for my car's gearing it's almost equalled out because the VE5 tranny has a shorter final drive, by ABOUT the same amount that my tires are oversize. so it ends up being just like a VG5 tranny on stock size tires.

i will be dropping soon-ish, and these wheels will not interfere with dropping. my old ones would have (well running neg camber MIGHT have gotten them inside the lip.. who knows). at any rate my current wheel/tire setup will be just fine for eibachs. part of the rubbing problem was that my rear struts are quite worn, so the car sags for any reason at all in the rear.

and yeah, lower profile makes the sidewall stiffer, but, so does using a 20mm narrower tire on the same rim. and i def wouldn't say that running 20" wheels on my car would improve handling... cuz 20" wheels are HEAVY and unsprung weight is your enemy when it comes to getting a car to corner well. i wonder how much matt's track wheels weigh... plus super-skinny tires reduce how much shock (pothole) you can take before the rim gets bent. and it makes the ride harsher.

 

dyam thats a fat spacer u were running there....i would never run something big like that...i am already running 300zx wheels with 25mm spacer on the rear and i m gonna reduce it to 20mm soon....

 

 

wow 3rd gens look good

 

so burhan... do you figure that with your current setup if you dropped it a 1.5" (i guess like 38mm-ish) that you might slam the fender on the tire as the suspension moves? it looks like the edge of your tread is directly under the flat lip of the fender. that why you're reducing to a 20mm so you can drop later?

 

Shweet ride mang I've always loved the 300 wheels on the 3rd gens..

 

correct, u got it

 

thanks Greeny, that is why i was waiting for 300zx wheels cuz i knew it would look gud......

Simply Looks Good.

 

heh, see i told you. are the 20mm ones the kind with studs in them already? or just holes? and didn't you say you had like.. 30 days or something to return them

 

yes, i am going to take studs outta the sapcers and machine the spacers to 20mm then i am using high performance studs or u can which can tolerate high tension. Total 20 studs only for rear, 5 for spacer and 5 for hub each side.there r press fit studs on spacers. After all dis m gud to go for real.


Dyam hard to write on iphone took me 10 mins to write lol



Edit: i am not machining my self, my machinest friend is doin it for me and which is in my college and hes becoming machinest lol

 

so you press-fit the spacers onto the rear, and then on top of that you still fasten them with lugnuts.. just like the 25mm ones you ahve now. it's a good design i think.. as long as they are hub-centric. i might use thin spacers on mine just to get them as far out as i can safely.

my 5th gen rims are 16mm closer to the body than my Chrysler wheels did... so i think a 10mm spacer will be safe for me... but these wheels aren't even in very good shape so i would really rather get a different set of wheels entirely.. like some 17x8's.

 

RPM @ 75 MPH please..

 

75mph according to the speedo? or 75mph according to radar?

me and you have the same gearing... but not the same tire size. so i turn less rpm to truly travel 75mph... but the rpm when the speedo says 75 is the same for me and you. so if me and you are running our cars side by side in 5th gear (or any gear), i will turn less RPM to stay even with you, because i have bigger tires.

but the final drive on the VG5 tranny IS longer than the final drive on the VE5 tranny, which i have noticed in that my rpm is always higher for the same speedo-indicated speed.

 

I want your RPM @ 75 MPH(of course on your speedo) ??

 

dunno right off hand. but it will be identical to yours, cuz we have the same tranny..... (remember i switched to a VLSD in october??) i'll just be going faster than you at "75mph" cuz i have bigger tires.

 

ugh..

just say iono?

 

the actual answer is "same as yours cuz we have the same tranny"

both of our speedometers are wrong though. mine's too slow. yours is too fast.

 

No doozledorf, your RPM's are different @ 75 because of your bigger wheels...

are you getting the picture yet?

 

not at 75mph according to the speedo...

think about what happens if the car is on jackstands and the wheels are nowhere to be found. turn car on, launch straigt into 5th and set cruise at 75mph on both our cars. our RPM will be the same. even tho the cars are travelling 0mph in real life.

75mph according to GPS or radar is totally different. that's when tire size comes into play. If i put monster truck tires on my car and ran the speedometer up to 75mph, i might actually be doing 100mph, but the RPM will be the same at a speedo-indicated 75mph.. but the car cannot detect its TRUE speed..

that's why i was saying that you have higher rpm if we are running side by side... but if we run our speedometers at 75mph, we'll be turning the same RPM as each other, but i'll be pulling away from you.
