rims and tires
so im planning on going to 35s here really soon on my jeep (1990 jeep cherokee) I want to get cragar soft 8s and im thinking 15X8s. So my question is if i run a 35X12.50 on a 15X8 rim what backspace do i need?? Also another question i have is what do i need for gears. My plan is to go 4.88s (also very soon) i have a d30 front and a 29 spline 8.25. So what all do i need to re gear to 4.88s? Im probably going to have the shop install the gears since i have no idea what im doing with them haha. any help will be much appreciated.

You'll most likely need a new carrier for the D30 depending on what your current gears are, the 8.25 doesn't have a carrier brake so you're good on it.

Okay so sounds like 3.75 for back spacing will be good? and lowrange2... why do you say i need different axels for the new gears? from what i understand the stock d30 and 29 spline 8.25 will be plenty strong enough for 4.88s.

He is probably right, but it's gunna depend how hard you wheel it. I have the same setup as you, and just broke an axle shaft. Big tires are hard on the d30. I was pushing it to the max and broke. From now on I'm just gunna use it for beach driving and trail rides. We'd all like duel d60s, but it's not always feasible to make necessary axle swaps right away.
