Default Tire question, very simple. Can you help?

I recently sold my falken 452 245/30/20 they were up front.

They rubbed.

AFTER MUCH READING AND SEARCHING the forums, I understand the bread and butter for my car up front is 235/30/20 if I dont plan on slamming.. However I want to know if that can be replaced with a 225/35/20....

Would I be in jeopardy in safety? anyone have some insight... ?

thanks guys


BTW anyone looking for tires.... tirebuyer.com already beats most plrices from other sites and FREE shipping.

Have you looked at a tire size calculator?

I have but I was hoping to hear it from someone who has had actual experience with this, sometimes those calculators cause a big waste of money.

The correct front tire sizes for the IS 250 (assuming the factory offset) is:

225/45R17
225/40R18
225/35R19
225/30R20

Definitely a pattern there! Depending on the tire/wheel combo they may rub with 235s and most likely will rub with 245s (as you have already found out).

You should be fine....the 35 will be ok since you're not planning on slamming.
