I'm torn...

18" Racing Hart CP-10's($1800 w/ tires)....OR
19" Konig Tantrums ($2400 w/ tires)...

Both are gonna need a "35" series sidewall...
so i'm guessing they'll have similar ride quality...

Input please??

Thanks.

I hope you dont plan on drag racing in either of those! But, Id take either set myself. Get one of each and Ill try the ones you dont end up liking

 

drag racing will be done on my stockers...
until im making enough power to overwhelm them of course...
then i will just get a nice set of slicks...

i think im just gonna get the RH CP-10's...
i like the style much better...

NOW i just gotta decide on the finish...
Bronze or White.
(My car's white...so i'm thinking Bronze).

 

only 18lbs for the 18".

 

I got 18" Lowenhart LDM's.. they are 3pc and are very light... if you get wheels that are too heavy your handling and performance will suffer. If you go with 19" you'll be paying about $100-150 more than 18" tires per tire so each time you replace tires you got to fork out over $1,000.00 for 19" tires.... something to think about.. I get 18" pirelli's P7000 for 159.00 each that's 636.00 plus 80.00 to have them mounted...

 

18's!!! But the ride quality is going to degrade.

 

Hey all,

Why does ride quality degrade with wider tires? Also ... I'm confused about dimensions ... what does 18x8 mean? What does my stock y2k max with the 17" 225/50 have? actually .. lol ... what does this mean?

 

18*8 means this, 18 is the diameter of the rim and 8 is the
width of the rim. for stock rim, the size is 17*7. and 225 is the width of the tire.
17-225-50, means 17 in diameter tire, 225 is the width, and 50 is the profile (the smaller the number then thinner the tire) thinner tire=better performance

 

First the 18x8... the 18= the diameter of ther rim in inches... the 8= the with of the rim in inches... so a 18x8 is 18 inches in diameter and 8 inches wide.
Now the Tire.... 225/40-18ZR... the first 3 digits mean the with of the tire in milimiters... the next two digits... 40 mean.. the ratio of the tire... that gets tricky... but the best way to do it is.... it's a percentage of the with... so 40% of 225 is 90... so the sidewall of the tire is 90 milimeters in height... so if you have a tire with a side wall on top and bottom of the rim..duh!... it's 90 x 2.. which is 180...
You use this to figure out what size tire you need when you upgrade your stock tires and wheels... you also have to figure out the diameter of the rim in mm... so multiply 18X 25.4 ( there are 25.4 mm in one inch)..457.2 is the diameter of the rim in mm. now add the tire sidewalls (2)..of 180 and you get...637.2mm that is your overall diameter of your tire and rim combined...
The ride changes because of two factors... the side wall is much smaller threfore it has less room to flex when you hit a bump or irregularity on the road... the second is that the Z rated tires are designed to be very stiff on the sidewall for better handling so they will flex even less... and you will have a hard time finding anything in 18" in tires that is not Z rated....
One more thing if you get rims that are cheap and heavy your suspension will have a hard time trying to keep the tires planted on the road at all times... more weight means bad handling and bumpy ride....

 

...what would the ideal.."best performance" rim weight be. the lighter the better I gather..butgenerally speaking, what sort of average rim weight should i be looking at?

 

You get what you pay for.... that's the bottom line... go to a reputable shop... or even the Tire Rack... they will give you #'s on all the wheels... but idealy... each rim should be around 20-24 lbs... that is a good wheight... there are some that are lighter..(Expensive) and some that are a lot heavier like 30+ lbs... these #'s are for 18's. for 17's it should be lower... but if you buy any rim from a solid Manufacturer... you wont go wrong..(BBS, Volk, Racinghart) there are others but ultemetly it's all about style...
