Im currently looking for some tires, and I wanted to get some input from any other 00+ Infiniti I30t owners and what size of tires they got of their I30t's.

 

If they're OEM 17x7 wheels then I'd go with sizes that are in spec.

i.e. 225/50/17, 215/55/17, 235/50/17

I run 225/50/17. Plenty of tire choices in that size nowadays.

 

I've seen on Ebay Infiniti I35 with 225/55/17+stock rims and i couldn't believe these tyres are not rubbing, because the overall lenght is too big...

 

Yeah it doesn't make sense to use that size.

 

Using stock size...works great

 

Whats the problem with 225/55/17+stock ?
If they dont rub I see absolutly no problem.

 

3.4% difference in speedometer and odometer readings would bother me. May not bother you, but it bothers me.

Play around with the different sizes with respect to the OEM size.

 

That's the question. Do they rub or not, because i haven't seen anybody on the org running with such a high-diameter tyre.
I would be happy to know the answer, cuz i'm wondering to buy 225/60/16 tyres, which are almost "same" as 225/55/17...



You are right, but don't forget that the speedometer do not show the correct speed(shows less MPH) while driving with 215/55/16 tyres! It should be better with 225/50/17 and probably, 215/55/17 is the correct size for our speedometers.....

 

True, I'm of the belief that 215/55/17 is probably closest to accurate, but in light of the lack of explicit evidence supporting that claim I can only base any different size tire difference on that of the OEM size.

In any case, I believe that 225/55/17 is still on the upper end of the scale.

 

So aside from incorrect speedometor readings (which dont bother me one bit), should I be worried about anything else ?

 

If they fit with no rubbing I would go for it. My tires I have on mkae mine 5.4% too slow. it doesnt bother me just means my odometer is going higher as fast which in return is a good thing.

 

My 2000 i30t has 245/45/ZR17 tires. Planning to change my tires and wondering if I use the same size. They are a little rough in city driving. Looking for something more smoother ride. Your expert comments will help.

 

245/45/17 is too wide for stock 17x7 wheels.

Go back to 225/50/17, 235/50/17, or 215/55/17

The latter two should be more comfortable.

 

Thanks MetaOrbit for your quick response. One thing I realized is :

For vehicle stock tire size 225/50/17, Speedometer difference = 0% & Diameter difference = 0%.

For tire size 235/50/17, Speedometer difference = 1.552% too slow & Diameter difference = 1.53%.

For tire size 215/55/17, Speedometer difference = 1.783% too slow & Diameter difference = 1.75%.

For tire size 245/45/17 (my current tires), Speedometer difference = 0.658% too fast & Diameter difference = 0.66%.

Taking these differences taken into consideration, which tire would be the best.
Also which ones would be cheaper to replace with and what brand would you suggest.

 

You'll probably find the cheapest tires in the 225/50/17 range.

But if you want most comfortable then I'd go with 215/55/17 or 235/50/17 as they'll have more sidewall.

I've had good experience with Kumho Ecsta ASX and Toyo Proxes TPT in 225/50/17 myself.

 

Would you recommend all 4 tires to be same or is there an advantage in having different tires in front and rear.

 

All 4 the same.

 

Well I installed the 225/55/17 Goodyears on my car and the ride as smooth as if its brand spanking new.
The ride is smooth, quiet and very comfortable, and I am very very satisfied.

 

I wonder if 235/50/17 tires would increase fuel consumption over the 225/50/17 noticeably. (10% maybe?) Out of these, which one you prefer?

Toyo Proxes 4
Avon Tech M550 A/S
Yokohama AVID V4S

 

Couldn't say on the fuel consumption, though I doubt it'd be that noticeable.

Out of those three I'd probably choose the Toyo Proxes 4.

 

Wondering if 215/50R-17 Kumho Ecsta ASX BSW tires are a good choice for 2000 Infiniti i30t.

 

what model of Goodyears do you have

 

They're a little thin. Have something against 225/50?

 

Comforted Assurace or something like that, I got a very good deal on them (120 bucks each).

 

The tires are Pirelli 210 Snowsport 225/55/R17 97H. The rims are ASA AMG look-a like. This set is off an S Class Benz. Used for about 3000 miles. Owner willing to sell for $550.00.

Wondering if I can use them for my 2000 i30t and is the price right for these tires.

 

Well you likely won't be able to use the wheels if they're off an S-Class unless they were also drilled for 5x114.3 mm. Benzs use a different bolt pattern.

 

Hi folks,
I am wondering if P225-55R17 BFGoodrich Traction T/A Tires are good for my 2000 i30t. These are used tires with average 8-9/32nds. rubber (really don't know what it means).
Please tell me your experience with these tires and whats a reasonable price I should pay to get these.

Thanks again for all your help.

4/32 is where tires should be replaced. You're not terribly far off on that.

The tire size has already been discussed in this thread. No need to go on that any further.

Check the Tire forum for reviews on that type of tire.

Reasonable price? Whatever you think is reasonable. I, personally, wouldn't pay very much at all for used tires.

 

Has anyone ever tried to run 235/55/17 or 215/65/17 on an I35? Mines an '03...wonder if they'd rub?

 

i got these ones:


there alot cleaner now
