Fitment help

[ogvon]

So, I run 215/35/18 tires on 18*9.5+22 wheels usually but, put 225/35/18 on the rear two b/c of a tire leak.
What I’ve read online is that the front is a 23’’ tire diameter and now the rears 25’’.
I figure I should raise the front coilovers then, to even it out.
My question is should I get an alignment after or is it a small enough adjustment to where I can raise the front to match rear and call it a day? Or is doing this pointless... Any help is appreciated

You should put the same diameter tires on the front. Your wheel speed sensors are going to lose their minds!

Yeah the ride height here is not the problem, the differing tire diameter is. This platform likes a square setup. Also how much of a stretch is a 215 tire on a 9.5in rim?

Where did you read that? Do they look like they're that different in diameter? Pretty easy to find diameters of tire sizes, most manufacturers publish them and Tire Rack also gives them.
Also, 215/35-18 sidewall height is 215*0.35 and 225/35-18 sidewall height is 225*0.35 so the difference is 10*0.35 or 3.5mm, so height difference is 7mm which is a long way from 2" (51mm).

Should be running 40 aspect ratio, not 35, to be near stock diameter. Also, Tire Rack shows only one tire available in both these sizes, are you sure these are the sizes you run?

Anyway, the one tire they have has 23.9" for 215/35-18 and 24.2" for 225/35-18. 0.3" difference in diameter, not 2".

I figure I should raise the front coilovers then, to even it out.

No. For one thing 0.3"/2, or 0.15" over the 101" wheelbase is small, and for another if you *raise* then end of he car with the smaller-diameter tires you'll double the additional wheel gap at that end which will look more awkward.

Not something I'd drive on that's for sure, manufacturers' recommended width for 215's is 7-8"
