What is the best size rim for the front wheels? What gives u better control/driving comfort? I am still in the deciding process of what wheels to get and want to know the effects of the diferent sizes of wheels. Can anybody help me out? thanks .

Woops, forgot sumthin, talking about width, not diameter.

 

well i have rims that are 8 inchs wide, and they rub when i turn all the way, and they are about 1/8 inch from the ground effects when turning

 

my 16x8 irocs work just fine with 245/45/16 tires, car handles fine, the guy that had the car before i did had some 255/45/16 on the front and rear, car handled fine, i just didnt want those tires cuz they were completely bald around the outside in the front.

A certain chain of events will occur when you are power-braking the car (1 foot on the breaks with the other foot giving it gas, this will stall the converter until its max stall speed. So the tires don't spin until the motor spins at the set stall speed. So you wont move until the motor spins faster than stall speed). When you finally get traction with those wide tires, something will break. But if you still choose to put massive meats on all 4s, the sizes are as follows. 1) (Front/back) The easiest approach is to install corvette 17x8-inch rims with 4.5-inch backspacing with 255/40 r17 tires. 2) (Front) 17x8 inch wheel 4.5-inch back spacing 255/40r17, (back) 17x9.5 inch wheel 5.5 inch backspacing 285/40r17 tires. 3) (Front/back) 17x9.5 inch wheel 5.5 inch backspacing 275/40r17 tires.

F-bodies have a tendency to peel the tires. This is good and bad, good because you can do wicked burnouts, bad because the tires slip too much on heavy acceleration. (But this can be good if you're making power and still using the stock axle). So you can bolt on traction adders and not get over zealous with the power, or you can keep the ho hum traction and buy a few more under hood ponies. Either way it's a trade off, your E.T.s will be similar anyway. *Note option 3 may require minor grinding of the outer tie rod ends to gain proper clearance.

 

so 17x8's on the front wont have any probs? wont hit the gpx or anything?

While I am at it, what are the different numbers for tire sizes mean? i.e.) 245/45/16. What do all the numbers mean? I have never understood it :-\. Thanks again for the info guys .

 

245 is the width in millimeters, 45 means the sidewall is 45% the width, 16 is the rim diameter

 

I have 275/40/17's on 9.5" rims all the way around, with no rubbing. Its all in the offset of the wheel.

 

hey MYBLUZ...is your car lowered at all?

 

i would also like to know if ur car is lowered, im planning on putting c5 rims on my trans am, but i dropped it about 1-1.5" and would like to know if i will have any problems in the future
