tire question

[wthayer]

hello, i have a 1988 comanche 2wd. i want to put 235x75x15 tires on it. i have 225x75x15 on factory rims now. i want to put 15x7 rims on it with the new tires. does anyone know what bakspacing i will need? i would like them to stick out a little but i don't want to lift it. thanks

if you're planning to lift it in the future then i would suggest to go with an 8inch rim, but if not 7 is fine... not sure on BS though.

what rims do you have now? you probably have 15x7. with 235's the tires will rub on the LCA's a tad...not much at all. i use stock wheels and i have 235's on both of my jeeps.

A 7" rim is a good width rim for holding a bead. I wouldn't go any wider on a tire so narrow.

To confirm what Twisted said ... unless your rims are the stock, base model steel rims they are 15x7. The stock backspacing is 5-1/4" and there are NO aftermarket rims that match that. Most will be either 4" or 4-1/2" backspacing. That's NOT a good idea, because they won't allow the tires to fit inside the fenders when the suspension compresses. You'll be banging the tires into the flares.

 

The stock rims have enough backspacing that they stuff the tires inside the fenders.

thanks for the info. i think i have the 15x6 rims. i will look for the factory 15x7. something better than i have now.

if you think those are the rims it came on from the factory it should say all their specifications on the tag inside the drivers door... mine has it all printed there.

my spec tag is gone. the rims are grey in color and have chrome trim rings with grey jeep center caps.

got any pics? if not i'd check the introduce your comanche thread and see if anyone else has them and post that pic.

my rims are the same as "attaboybob"s truck.

I don't know what "attaboybob"s truck looks like.

 

Steel rims have the size stamped into them right next to the valve stem. Take a close look, it'll be stamped either 15x6 or 15x7

i just found crager wheels 5 on 4.5" 15x7 5" backspace $34.99 from quadratech. these should do the job. they are only 1/4" difference in backspace from factory rims. thanks for all the info.
