Rota RB and RBRs group buy chime in here "tire size"

[wigenOut-S30]

Hey guys, I got the Rota RBR's from the group buy recently and I am really impressed with them and thanks very much to Chris for all his hard work! I think we should have a thread about tire sizes and what people currently have and Data to go along with it. Pics are welcome as well! Here are the tire sizes I have been thinking about. It seems that the 255-40R17s are a little too wide up front and rub on some things. Other things we can discuss is: When running a smaller tire up front.. will that cause understeer? Thoes who already have these and logged some miles on them.. has that caused understeer?

 

275-40R17 = 10.8 wide and 25.66 Tall Rears

 

245-45R17 = 9.64 wide and 25.68 tall Front

245-40R17 = 9.64 wide and 24.71 tall Front ------ Not sure about what to run up front------

255-40R17 = 10.03 wide and 25.03 tall Front

I am a little on the fence with going to a 245-40 or a 245-45 for the front. It seems that the 255-40's are a little wider and seem to be a problem rubbing on things

My plan is to run 245/40R17 up front, and 255/40R17 in the rear. Trying to keep the diameter down at both ends.

Where did you get that it rubs?? my 255's up front don't rub at all.

I'm going 275 on the rear, haven't run the set up yet though. Car is kinda in "parts"

the 245-45R17s rub the front fender just a little. and from what I read the 255-40s might touch the sway bar and the tension rod? When I remade my battery box I made it come down to far and the 245s were all in it.. so I cut out a triangular section and welded in new metal.. It clears now but not sure if the 255s would clear.
