guys i actually have 18 inch rims, 9.5 front and 10.5 rear .
tires are 245/40 F 275/40 R

suppose i want to install 295 @ the rear, what are the correct tire sizes that would keep me as close as possible to factory specs

Any recommendations for tires? Currently I am running Continental and they are litterally ripped off after a short track session.

P.S: I'm running Tannabe springs GF210.

 

offset?

 

+ 28 for the 9.5 wheels (front, im using a wheel spacer )

+ 30 for the 10.5 wheels (rear)

 

anyone?

 

Bump!!!!!

 

I think 295s in the rear would throw off the balance of the car and give you more understeer. I suggest you stay with the same size and go to a better tire with more grip.

 

This is a somewhat confusing statement.

Do you mean stay with the same sizes front and rear, but select a tire with more grip? Because if you mean just the rear tire with more grip, that would do the same thing you describe and just increase the understeer.

 

sorry, i see this topic and I have my stock wheels 18x8 front, 18x8.5 rear
can i change tires to 245/40/18 F and 275/40/18 R? do i need wheel spacer? please help

I plan to drop 1' around w/ eibach prokit springs

 

NO , you rear wheels arnt wide enought

 

I think he meant to just get some sticky tires in the sizes you already have. F that . 295/35 rear and 275/35 front and you'll be fine.

 

Im running a 245 front and a 295 rear no problems

 

http://www.sportcompactcarweb.com/pr...t_2/index.html just go ahead and read , you have problems and just dont know it.

 

that is a great article, thanks for the link.

Having the same section width on the tires make sense to move some of the grip forward. I used to read a British tuning magazine, and one of their recommendations for reducing understeer on frontwheel drive cars was to run one tread width wider on the front than the back.

 

Haha they are a joke. ( for instance their project car is at VRT )

All I Do is drag race, As long as the diameters are right then I dont really giva chit.
