OZ wheels 17x7.5 best fit with which tires?

[newkid185]

Hi guyz!! im about to get 4 OZ Alleggerita HLT in 17x7.5. The recommended tires that tirerack advises is 225/45-17 which i found its kinda thick (45 of 225 is about 101.25 ) Which other tires that i should go with which its not too thick and still perform well?? and how about if i get the 17x8??

I would use a 215/35 or 215/40 personally regardless of if u got 7.5 or 8s... Each to there own

These are the same wheels I've been looking at or the OZ Ultraleggera. Why don't you get them in 18x8, as you can have a bigger tyre later on without changing the wheel and it's only a little heavier. Myself I'm thinking 18x8 with 215/40.

If you are looking for performance there is no reason to go with the stock width tire on wider wheels. 225 or 235 width tire would be right for that size wheel. Never been a fan of the stretched look, function over form, but I'm an engineer so that's what I like.

for another viewpoint from Andy Hollis:

The tendency is to cram the widest legal tire on the widest legal rim that will fit and go for it. But that is not always the optimal solution, as street tires do not have the same super-stiff sidewalls as do the best R-comps. Sometimes it makes sense to run a narrower tire for a given rim fitment. From the testing we've done, we find that a good rule of thumb is that the optimal rim is the same size (rounded up to the nearest half-inch or so) as the tread width (not section width!).

You should read where Andy does talk about the Star Spec being an exception to this.

With that said, 17x7.5 with a 225/45/17 should fit well and work well.

When my stock tires wear out, I'll be running 225/45/17 or 235/40/17, depending on what tire I go with. I running 17x7.5 oz wheels too btw. I'm not really sure what you mean by too thick?

I'd be willing to bet a 235 high performance tire with same overall diameter will run faster than the same tire in 215 on a 7.5" wheel on an fr-s or brz.

That is faster on a road course or autocross.

I'm not taking that bet! But a year or so from now we should know from real experiences

thick in here i mean the sidewall, if i go with the recommended tire for 17x7.5 the tire will be 225/45 so the sidewall will be around 101.25 and personally, i love to see a lil bit less than that...i tried to look for the 225/40/17 tires but theres none, they just have the 225/35/17 from yokohama.

Most people who have changed wheels think 18's are the perfect size for this car and even Toyota had 18's on their promo car.



18's only add little bit of weight over the 17's, both are still lighter then the stock wheels.
At the end of the day it's all up to you if you like them and don't regret getting them in 17's or 18's.

As I've said above I'll be most likely getting the OZ Alleggerita when I get my car as they are light, affordable and look pretty sweet .
As for size I'm going the 18x8 as it offers more tyre size choice (If you add more power to the car later on this will be important/helpful).
I also have some 235/40r18 on my current car which I may use (save some cost and to use the remaining rubber on them up ).
For new rubber 215/40 should work well and should have little stretch if any (8" is 200 & the tyre is 215 (it's bigger)). These 2 options should make your new wheels 2-4lbs lighter then the stock ones without spending big bucks.
