Does 245/35/19 fit on the front wheels? or I have to go with 235/35/19?

 

I just picked up my G37 yesterday (Sport, red/graphite, 6 speed, Premium, Navigation). I switched out the tires from the OE Bridgestone's to Michelin Pilot Sport A/S all around. In front I mounted 245/40-19, and they fit the front wheels perfectly. The 245/40-19 tire actually is spec'd to ideally fit an 8.5" wheel, which is what the front is (on the rear I mounted 255/40-19).

The usual guidelines are to not deviate from the OE sidewall height by more than 3%-4%. The OE 225/45 front tire has a sidewall height of 101.25 mm. The 245/40 is 98 mm, more than close enough. But the 245/35 is only 85 mm, more than 15% less than stock.

 

thanx alot for your info.

 

If you want 35 profile tires, you could do that with a 20 in wheel. The difference in overall diameter between a 245/40 or 225/45 and a 245/35 is about 30 mm (15 mm sidewall x 2). 1 in = 25.4 mm, so a 20 in tire with 245/35-20 will have approximately the same diameter as either a 225/45-19 or 245/40-19.

 

ohh no
im not planning to go bigger. im staying at the same size. but just wider.
im getting 245/35/19 on the front and 275/30/19 on the rear

 

Those sizes are wrong - The widths are OK, but the aspect ratio is wrong for your application. The OD of your wheel and tire combo will be 1" too small. You need 245/40/19 and 275/35/19.

So tats bad? I dont think so. coz I know alot of people ran the same size on M3s. I dont like thick rubber looking when I have 19s. Its just the tires are thinner than usual. And if I drop it more they would even look better.

 

Your speedometer will be off as well if you are not using the stock tire OD.

 

yea i heard about tat before. I think it was kinda off by a lil bit on my 3 series. oh wells shouldnt really do any other harm than tat. haha.

 

Your car will not look any lower or any better if you have a smaller side wall. You will just have more gap between the fender and the tire.

 

Well, this is half right. The car will sit a half inch lower because of the 1" decrease in the diameter of the tire wheel combo. However, unless the car is lowered the tire fender gap will get bigger. If the car is lowered, the lowering coupled with the decrease in wheel OD will turn the coupe into a lowrider or rice. You'll also lose ground clearance.

Hey, it's your car, if you want to rice it up, be my guest.

How would tat consider rice when i consider a thinner tire wall when i wanna go more low profile than others? wut kind of logic is tat?? lol?

 

what kind of english is that? If your leaving the car stock height but just putting thinner tires the gap will be bigger in the fender wells. The car is not getting any lower in the suspension itself. Only a little lower from ground clearnence due to thinner tires. The suspension is still at the oem standard height.

 

well offcourse im lowering the car. I just have to stand the wheel gap for a couple days so i can get the springs installed from eibach. thanx for watching for being rice. dont worry i will never turn my car in to a rice rocket. The new rims went on, but i have to sell them. I love it but the offsets just way off. they stick out about an inch in the rear and half an inch in the front. so.. gotta sell these.

 

if your lowering your car and depending on how much you plan on dropping it you would have to reduce your side wall size. i ran into this problem when lowering my M3 I used wider tires with the correct sidewall size for the oem specs. But when i lowered the car the tires rubbed the fender wells because the side walls where too high for the amount i dropped the car....
