I don't think so... But don't take my word for it....

 

the best combo to keep everything happy and look the best on an 8.5" front and 9.5" rear is a 255/35/19 front and 275/35/19 rear - they both give you enough sidewall where the ride is not super stiff, and they're approx. 0.6" difference in diameter - I will be running these sizes in Toyo T1-S's on Axis Hiro's come the end of the summer...

 

I just put 255/35's in front & 275/35's in the rear. It's only been a week, but so far no problems. I will take some pic's this weekend and post them.
