When you say "it depends if your rear wheels are set up right" Do you mean the offset? If you do, my offset is +27 on the 19x10 rear. I haven't bought the tires yet and want to make sure I get the size right.

mario, it's your call. for sure 275/30/19 will work for your 10+27 no problem. i know it works on the 10+24. however, if you put 285, yes you have the "right" precie sidewall, but the tire is wider and so the stretching is different. i am not sure if you will rub or not.

i have 285/30, but that's on 10.5 so i have more stretching too to avoid the rubbing.

so you see how "difficult" and "tricky" it is on rim and tires? don't even ask me to throw in the brand/model difference

I think I should play it safe and stick with the 245F and 275 in the rear. As far as the 3mm difference. do you think this will be noticeable to the eye ?

no the difference will not be noticeable at all. however, the 245 is perfect for 9 and 275 might be a bit stretch to 10 (depending on brand and model). if it's stretched, then you might think the rear tire has lower profile

btw, for my sc430, i have 255/35 and 285/30. dont' ask me why, that's the only combo avaiable for the tires i got

This is the best thread I've ever read on the tire and rims numbers.........I actually understand it now. I'm buying some 20" Maya EX2 from someone when I find out the rim width I will be getting back to you guys, because I'm told they need tires.

So Henry yes I am going to dare and ask, What brand and model rubber do you reccomend on the Sc with the 245, 275 setup to minimalize any look of stretching? Since different tires have different profiles there must be one that looks better with this setup?

hey no problem man, there is no dumb question, it's only dumb when you dont' ask and do it wrong

Here you go Henry, 19 x 9 +28F and 19 x 10 +27R so what do you think 245F and 275R?

Ok, help here, I have 20X9 and 20X10 rims, what is the tire size recommendation? The previous setup were Falken's, 285/30zr20 rear and 255/35zr20 front.

mario, i think with 245 and 275 you are VERY VERY safe. i think you can go with most brands too

PROY, with 9 and 10, i think you can do 245 and 275 to be safe, but you can do 245 or 255 with 285 in the back. but you will have to check the offset to make sure it's good

That's close to my next set of tires... 245/30/20 & 295/25/20.

whats the downside of going bigger than stock. So if you didnt want to ride of rubber bands. Cant be that bad can it? I am just thinking the speedometer might be a few off as well as make the car a little slower.

if you get wheels of larger diameter (read, i said wheels, NOT rims. rims + the right tire could mean same diameter), the speedo is off a little. and they might be heavier so more stress on brakes, meaning brake fade might hit sooner. also you need to pay more attention to the tire to make sure the pressure is good and there is no flat tire. and ride will usually suffer as you go lower profile. bending wheels is a bit easier in general so getting strong rims is a must. and of course it's easier to curb the wheels
