been doing research on why i see most ppl gettin 245/35 front and 275/30 in rear... shouldnt it b 255/35 and 275/35 i talked to many tires dealers and got many diff answers... which is better 245/35 275/35 or 255/35 275/30 also which is better for 20's 30 series or 35?
by the way my rims are 20x8.5 +25 20x10 +20

 

20 30 or 35 series doesnt really mean much.

they are aspect ratios. They depend on the width of the tires.

Also, you cant really just choose whatever you want, unless you want to mess up the speedometer. With that said, there are many different combos you can do.

try messing around with a tire calculator.

i understand that, thats why im askin for opinions in here as to what tire combo is good to go with...
thanks for the input

 

I think you are lost. Tire width is variable. Pick a number.

Overall tire height should be the same as the tires on the door sticker.

 

Examples can be found here: http://www.*********.com/zwiki/G35_O...Wheel_Overview

Nissan puts a 265 mm tire on a 10.0 inch wheel.

Its probably a forbidden site. Don't know why. Hope I don't get into trouble.
