Does the width of a tire need to be considered when going to a larger size and regearing or just the height? For example, I have the 3.73 gears, if I went to a 33x10.50 would I be able to run with my current gears better than I would if I went to a 33x12.50? Or is it a combination? Just curious.....

although adding width to tires would give more traction and make you want to regear more, I doubt you would lose any power unless the diameter of the tire (height) was changed. maybe aired down the height may be different though. let some of the others chime in

The width of the tire has no bearing on the gearing. Only the diameter. You will not like 33" tires with 3:73 gears . While in town you will not have much concern, you will out on the road at highway speeds. The larger tires drop the RPM's down so the Jeep will lug under power especially up hills and into a wind. The overdrive will keep hunting all the time as well. I run 32" tires and regeared to 4:56 and it has helped alot.

I run 32x11.50 now with the 3.73, its a little slower on the highway but nothing I can't live with, i just wondered if the gearing was more in relation to the overall mass of the tire versus just the diameter.

Yeah, the gearing is all about the diameter. But you will want to keep in mind that a wider (and taller) tire adds weight, and therefore increases stopping distance. You don't want to find that out the hard way.

wouldn't a wider tire decrease stopping distance with the increased traction? I understand if you are saying a taller AND wider tire. . but width alone, don't you think the added traction will circumvent the added weight (at least until you start widening 34+ inch tires)?

Nope. Added weight anywhere = longer distance to stop. 1" Wider tread will not offset the increase in lbs. (or kgs. for you Canucks) in my opinion. We are talking about a difference of a few feet at most, but noticable to someone who drives the same vehicle every day. My wife hasn't even noticed, but I felt it right after I put on the larger tires. It takes a couple extra feet to stop at the intersection. I have had to adjust my braking, and don't notice it at all any more. |

A 33x12.50 tire WILL make you want to regear more then a 33x10.50 tire. I know this from running both. A 33x12.50 is much heavier. That 2" in width makes a bigger difference then most would think. The weight is the biggest factor in slowing your acceleration down and making your braking worse. A heavier tire is worse on steering, brakes, etc. The biggest difference was the acceleration between the 33x12.50 and 33.10.50 IMO. The stock Rubi gearing has worked fine for me with the 33x10.50's. That said, it's a Jeep, I don't mind it not jumping off the line, I will be moving up to either 34" Trxus or 35" BFG's with the stock Rubi gearing until I can afford some 4.88's.
