Tire/wheel help for YJ/Liberty

Hey all...

2 questions: I have a 93 YJ that has never been lifted in any way. I have Michelin 235/75 R15's on it now, but they need to be replaced soon. Can I go any bigger without a lift? There seems to be lots of room around the existing tires as it stands now. Your thoughts?

Also: I just bought my wife a red 2003 Liberty..the dealer has offered me the option to upgrade the wheels right off the bat, and said I could pick just about any style (I think he has some connections)..I will be keeping the steel rims and getting winter tires..so my question is...what style of wheels look good on the Liberty? Any recommendations?

Thanks!

Frank

Okay, everyone.. I've got another newbie question for you.. how do these 30",

31", 32" etc sizes related to 215, 225, 235 etc sizes?

Approximately 10/9/03 10:41, Saigoncal1 uttered for posterity:

215,235, etc. are just the width of the tire at its widest point and nominal inflation. The next number, e.g. 235/75 means the tire is 75% as high as it is wide. The last number, e.g. 235/75-15 means it fits a 15 inch rim. From all of this you can calculate the tire size but there is a lot of slop in the sizes so the makers just assign the nearest common value. Much easier to use tire rack, etc. and get the tire size, from which you can get the actual tire diameter... which is the same as used in the 30, 31, 32 type sizing.

Again even in the 30,31 type, the maker just picks the nearest size which is usually close enough.

e.g. Pirelli Scorpion AT:

235/75SR15 is 28.9 inch diameter 30X9.5SR15 is 29.6 inch diameter.

The 235 etc. number is the width of the tire in millimeters.

The 60, 70, 75 is the aspect ratio, which is the ratio of the height of the sidewall to the width of the tire. This needs a decimal point in front of it, so 70 ratio = .70.

To calculate the tire size convert the width to inches by dividing by 25.4 (235/25.4 = 9.252)

To calculate the sidewall height, multiply the width by the aspect ratio. (9.252*.70 = 6.476)

The tire height is the rim diameter plus two sidewalls. (6.476*2 + 15 =

27.95)

you can also go the other way:

To convert a 35" x 12.5 x 15" tire to metric:

Take the width and multiply it by 25.4 (12.5*25.4 = 317.5) This tire would be designated a 315

The sidewall height is (35-15)/2 which is 10"

The aspect ratio is sidewall height divided by width, so 10/12.5 which would be .80 or an 80 series tire.

So this tire would be designated as a 315/80R15. The R designates radial.

and if all that confuses you, here are online converters:
