I have a set of Varrstoen ES1 18x8.5 on my TL, which currently have 225/40/18's on them. The tired are stretched with this size. I am lowered (but not slammed) on Function and Form coilovers (hoping to upgrade to Tein soon). The ride is currently fairly rough and I'm not sure how much the tires being stretched is impacting the ride quality as I bought the car with this setup on it. This is the first time I've had stretched tires on a car, but I assume the stretch makes the sidewall stiffer, which may be contributing to the harsh ride.

I don't really love the exposed rim look of the 225, so am looking into getting a 235 or 245. Will this improve the ride quality much? Could I have any rubbing issues with either size? Should I stick with a 40?

Thanks!

You might rub but the car should ride a bit better. Make sure you get an alignment afterwards too.

 

Ok, Thanks! Now a new question. It has 2 new tires and 2 that need to be replaced. It would obviously be cheaper to just put 2 on the same size, but that doesn't help the ride quality. Should I just put 4 235's on and pay the extra $ or get 2 225's to save the $ and then put 235's on in a few years?

Just hate to waste the $ I spent on the 2 new tires that are only a few months old.

 

^maybe sell the tires you bought a few months ago on Craig's list or Azine Black market? Recoup something towards the new tires....
