I am looking for advice on moving from 31.5" tires to 33" tires. I would love to hear from folks recommendations.
I drive off road in the mountains of Colorado, but not aggressively. This is a daily driver that sees about 4-6 weeks of offroad (meaning trails) a year, with various other dirt road outings.
I currently have no lift, running stock axels 30F/35 rear, with I suspect either 3.07 or 3.73 ratio. My TJ is a 5speed manual with the I6 engine. I have Poison Sypder customes tube fenders in the front and rear, so I don't need to worry too much about fender clearance.
When I went to my current tire size, I noticed as significant reduction in "power" resulting in losing the use of 5th gear on highway. From my reading, this likely means I need to regear to a more beneficial gear ratio to get back use of 5th, and to be able to actually climb hills not in 3rd gear (on highway).
I would like to go to 33" tires to match our Full Size Bronco and off-road trailer. I would like to have a standard size tire so I can swap tires if required. Additionally, the increase clearance would be nice.
The question I have is if I will need a lift, and if so, will I need to have a suspension change. It seems I may be able to go with an upgrade in the axels when I do the gearing change (looking at the Super 35 + detroit locker + 4.56 ratios) and a simple change up front to 4.56. However I am not sure if I am going to now change suspension/shocks etc. Any advice on how to limit the cost for getting into the 33's without causing a lot of breakage on the trails?
I will also point out I take it fairly easy off road, and rarely seek out challenging terrain. However I am pulling a utility trailer off-road often (about 700lbs).
