No, bolt pattern does not match. Our bolt pattern is 5x4.75. Those are 5x4.5. Also the backspacing might be cutting it. I'm sure others will low backspacing will chime in.

3.75 of backspacing will eat hub assemblies and really put a strain on your power steering. I've developed a nasty power steering groan since putting on my 4.5' backspaced rims, I'm just waiting till after finals and we'll see if a switch to Royal Purple power steering fluid helps

think that would fix the issue with no need to switch to synthetic?

the groan is generally strain. Could be due to low fluid level, or poor lub properties inte h pump.
price em out and see which way you want to go.
Power steering pump only holds liek 2 quarts of fluid, so it should be that much in cost, howver drainign the power steering might be another issue.

Get THESE instead. Same rim, just in the 4.5' backspacing, so you'll save your hubs/bearings/steering.

not a stupid question.



Backspacing is the distance from the mounting face of the rim (where the rim touches the flat surface of the brake rotor, on the outside of the axle), to the back edge of the rim. So a stock blazer that is 4x4 has 6' of backspacing. This means the backside of the rim is very deep. If you get a rim with 4.5' of backspacing, the rim is 1.5' shallower on the backside than a stock rim. A 3.75' backspaced rim is 2.25' shallower on the backside (meaning your wheel sticks out 2.25' wider!)

The rim pretty much acts like a lever the farther out you go. If you went with a rim having 0' of backspacing (lawn mower wheels?), all the weight of the vehicle is very far away from the center of the axle. This makes the force GREATER on the center of the axle (differential). The effect is the same on the wheel bearings and ball joints, but not as extreme of an increase like the differential would see.

ERGO....the closer you stick to stock spec's, the better it is for the vehicle. Keep the backspacing closer to 6', but still giving you the wide stance look that you want, and you'll be fine
