Ive ran 235/45/17 on mine with no problems for the last 3 years. i have 17 by 9.5 driftZ gtr rims with a 2 inch drop on D2 springs with tokico blue struts. I clear every manhole cover in town. =)
Note to some who may remeber. i did say they were 10.5 and they do look that big but the company only makes them in 9.5 widest. so i retract that incorrect statement. but they are 9.5. i finally tracted down the paperwork for them from my old job. I'm upgrading to 18x9.5 xxr wheels very soon...gota clean up that last inch of gap. hehehe.
