It's about that time again, my rear tires are all bald or chunking, and my fronts have started to show belts after last weekend. I was just wondering what the tire size consensus is, if any. For those who don't know my car, it is a 99.8% stock power 240, probably about 135hp to the ground. I'm looking at buying a set of Kumho MXs for my Z wheels and the cheapass inside of me (I own a 240 after all ) says to save $50 and get the 205/55/16, they'll be fine for my power level. Of course, i want to put the 225s on there.

...so the question i pose, would 225/50/16 make much more than a negligeable difference over 205/55/16 for my car (weighs 3000lb at the starting line, with upgraded shocks/springs) for a tire such as the Kumho MX? The followup would be at what point is the tire too wide? It seems like a lot of cars could run wider tires, but don't.

 

id do 225s...

what WIDTH are the Z wheels? That'll tell you how much width you can run.

 

z wheels are 7.5
225s fit nicely
....well, some 225s, others seem to rub on the struts.

What size tires do you run on your mr2?

 

yeah... i know for sure that Brian Davis and a few others have run 245s on S14. Maybe spacers would help give it enough clearance?

245s would work... not ideal, and honestly, i don't know if it'd be worth it for you. 225 MXs would be a very good combo though, IMO.

 

oh...

my car is ~2550 lbs in full "lightweight" mode, sunroof out, millenia/kosei wheels, Hoosiers, sub out, etc.

205/50 front, 225/45 rear

115whp, 130 rwtq

 

Ok, thanks for the input
245s would definitely rub without spacers, the 225 goodyear eagle f1s I have on now are like .5mm too wide......if they didn't have any raised text on the sidewalls I would be ok.

 

yeah....already taken care of
Good thing I have adjustable camber plates up front.
