Noob with tire questions

hello all,
I just picked up a '94 wrangler that had 36x15.50-15 mickey thompsons on pro comp 10x15 wheels. yea......looked great but these meats are just tooooo big. Sold the tires and wheels and started shopping.
my question is:
what is a decent size tire i can run to do trail riding without rubbing or cutting them up? i have a 2" body lift and i really do not know what suspension lift it has because it has the pro-comp coil conversion front & rear. i like the super swampers but unsure of what size tire to be safe on 10" wheels.
any help or insight is appreciated.
Dave

The infamous pro comp coil conversion kit provided ~5" of lift. Add that to your BL & that gives you ~7" depending on if it has sagged or not.

I'd run an 15x8" wheel with ~3.75" back spacing & maybe a 35x12.50x15 tire. If you have the stock rear axle (D35C) I don't recommend that size tire on that rear axle.

Thanks Joe,
i have the dana 30 in front and an 8.8 in the rear. it was hard to judge having the 12" wheels and 15.50 tires exactly what to go with. if i were to use a 10" wheel with about 4" of backspace do you think i could get away with some 35's and not rub or do you think i should shrink the back spacing a little to keep from rubbing?
i just want to do this once and not be sorry with my choice.

I got in contact with the guy i got the jeep from and he is telling me that the coil kit he installed is 4". that gives me a total of 6" to play with......so to speak.

with 6" I would say 35x12.50's on 15x8 rims with 3.75 backspacing. flex it out and adj the bump stops if needed. I would also upgrade the front axle shafts to alloy..with that tire size.

I have always heard (and seen) the 5" coil conversion kits. I wasn't aware they sold a 4". Perhaps it was a limited run.

I was told that my dana 30 front has the one piece alloy axles so i assume i will be o.k.
another question on the wheels. are there pro's/con's between using the 8" wheels vs. the 10" wheels. i found a deal on some 10x15 (4" backspace) steels and was planning on buying some 35x12.50-15 swampers.
will i have clearance issues using one wheel vs. the other with 35's??
i have fender flares on it but the last thing i want to do is have them get ripped off by the tires.

**** disregard the tires in this pic - they were M/T 36x15.50r15LT and waayyyy too big. that's the reason for the switch***

Those tires look perfect to me...lol

If your running this thing on the street as a dd I wouldnt get swampers. You will go through 1600 bucks worth of tire in like a year... If your not running it on the street, is there such thing as too big of tire???

One of the best things about the wrangler is the manuverability. If you run big tires without the right backspace you wont be able to turn as sharp. You could get spacers to go with the 4" backspacing but would it be cost effective?

I like 8" wide wheels for the size tire your talking about cause they hold the bead better from my experience. I have 35x13.50-15 on 8" wheels with 3.5" backspace and it just barely rubs at full lock...

It will not be a DD but will be driven on the street at times. After reading up on the swampers i will agree with you and have since then decided on going with a set of 35x12.50-15 BFG mud terrain KM2's.
I really liked the looks of those M/T's but they were 15.5" wide and i thought for sure when i was on the trail and articulated it would not be pretty..lol
Those were 12" wheels with 4" of back space and i could go full lock without rubbing. I am going with a 10" wheel now with 4" backspace so i assume i will be good. The street vs. trail ride ratio for this jeep will be at about 75/25 (75% being street).
4WD parts here in N.E. Ohio is running a great deal on these tires and others (shipped free) right now if anyone is looking for an early Christmas present from you to you.

after driving myself, and my wife nuts the last couple weeks looking for tires i have settled on one. Sam's club is running a rebate on Goodyear tires so i am going with the Wrangler MT/R with kevlar in a 35x12.5-15. all four mounted, valve stems, tax, etc. out the door for $975.
i was going with the BFG mud terrain up to this point but have read great reviews on both tires so i figured i might as well go with the best deal right now.
i also found a set (4) of Crager soft 8 (15x10) wheels on CL for $100.two of the wheels had gumbo monster mudders with a little tread left so i picked them up and gave the wheels a cleaning and some new paint. then found a single soft 8 wheel on CL for a spare. I will keep one of the gumbo's mounted for a spare and use the other four for the Goodyear's.
merry Christmas & happy new year to me!!

I like what you came up with, I know a lot run 12.50 on 8" rims. I don't like more than 2" more tire than wheel, it will drive much better on the road that way, in my experience any way. On rocks 12.50s on 8s may be better, I run in mud [Cat Island Swamp] not rocks.
