How do you measure to order to do 'proper bump-stopping' for the size tire you are getting? When I get my tires I would like to add the bump-stopping at the same time so how do I know how much more bump-stop I need and what are good places to go to find quality bump-stops?

ignoring the point that your cherokee should already have 15" wheels on it, the biggest tire you can fit without trimming/lift and no rubbing is a 235/75R15 tire

NewKindOfClown

15" is the stock size. Passenger tires, you're looking at 235/75/15. Some people put up to a 31" on stock, but that gets a lot of mixed replies and it depends on what your particular XJ wants. 235/75/15s will, in my opinion, fill out fine for stock height without trimming.

You either limit according to tire size or shock compressed length (whichever is the least distance). If you're using stock style shocks, this usually means to increase the bumpstop amount by 1/2 the increase in tire diameter to avoid rubbing, but the amount will vary by how much trimming you have done, and the shocks you will be running.

It's a 01 cherokee limited 4x4 came stock with 16's so I was looking to use my other 15's to save a little money!!! Thanks for all the help.

Skipper

All kidding aside I ran 235/75/15 with a stock suspension for a year and had no rubbing at all.
They look good on the rig and filled the wheelwells without rubbing even on full turns and flexing.

Thank you so much! Just want more rubber from the ground to the rim thats why I was down grading my 16's to 15's. Plus my 16's are 7inches wide. Looking to make it more beefy lookin without the lift

Hope im doin this right.
Did a 4.5" rc lift just dont know waht tires to buy. want somthing thats good on highway but still agresive. any sudgestions. also should i go skinny or wide? want to get 33' tires

Skipper

I run with a guy that has 33x12.5 on a 4.5" Rusty's lift with a little fender trimming and he does great with this setup.

dukie564

IMO 33x12.5 is way wide for daily hwy/trail use. I suggest a 33x10.5 for a good balance of gas economy and traction on the trail. Wide floatation tires aren't needed or desirable unless you do a lot of sand running.

But yes 33s will fit fine with a 4.5" lift and minimal fender trimming along the edges.

My personal recommendation for tires is Firestone Destination M/Ts. I've run them for over 2 years and recommend them to everyone. Excellent treadwear (55,ooo miles on my last set - on the front wheels!) and wet/dry/mud/snow traction.

Hey guys i found some 31 by 10.50 by 15. I have a 98 jeep cherokee its not lifted and im concerned if the tires will fit okay or if they ill rub badly ? Right now i have 235 by 75 by 15. Also could some one explain to me how i look at those 31s what size is that compared to 235 ? Reason im asking is if found 4 of vgc all terrain tires for 250 and that looks like a good deal to me.

Nperryman

Those tires will be around 2" more in diameter than the 235's you might need to trim. Go with a budget boost.

dukie564

They will not fit without a lift. 30x9.5s are the max I've seen work on stock lift - and they rubbed at full lock.

For reference a 235/75R15 is 28.9" tall and 9.25" wide
a 31x10.5x15 is 31.0" tall and 10.5" wide

This outlines tire differences very well:

Skipper

So no good way to tell before I add the tires.
OR could I see if the bump-stops hit before the shocks bottom out and if that is true then add 1/2 the increase in tire size which now that I am writing it makes perfect sense.
I have upgraded shock that came with the RC 3" lift so I should check to see what hits first, shocks or bump-stops.

huntsman

a okay i actually looked at this thread and the guys managed to fit 31s
