RE: Ice Storm 2005....HELP!!!!!!!

I want to run a poll on tire size! What I am thinking about is putting 35 inches on a 1995 YJ. But I only have a 2.5 not a 4.0. So what do you think about using 35X10.5X15 instead of 35X12.5X15? Super Swampers.
 

By just saying "Super Swamper", I'm assuming you mean the original TSL or one of it's variants(TSL/SX or Radial).......if so, the only 35s available are the 15/35-15 or the old Q78-15. The Q78 is only about 10.5" wide with a 9.5" tread, and about 35.5" tall. The 15/35 is about an inch shorter, 4" wider, much heavier and it requires a wider and heavier wheel. Of those two, I'd recommend the Q78 on an 8-8.5" wheel.

I'd rather use a 36x12.50 on an aluminum 10" wide wheel than a Q78 though. The weight difference is minor and you get a tire that is almost an inch taller and a tread that is an inch wider.The lugs are bigger and the 36 also has a cross-section that is 2" wider than the Q78, providing slightly more flotation in the soft stuff and a softer ride.

If you rockcrawl, you could justify the narrower Q78 over the 36x12.5 because of the increased contact pressure, but I'd personally choose the 36 for a great all-around tire. I pushed a set just fine with my 93 2.5l.
 
RE: sorry guys (ellipses)

Junkpile what gear ratio did you have to use to turn thoughs 36ers
Stock or did you upgrade. Just trying to learn
 
Have you considered the 34x10.50 LTB or the 34x9.50 Narrow SS (both Interco Super Swampers)? If you have stock gears on that 4 popper they may be a better choice. One of those choices are what I'd like to run under my YJ when I get it on the road.

How much lift is on the YJ?

I don't like huge jeeps that can easily go over any obstacle. Put some challenge into it and get the smaller tires!
 
RE: Re: New Member...

Stay skinny with the 4banger, less rotating mass and less wind resistance. My next tire may be the TSL SS (Special Service) in 34x9.5, it's got 27/32" tread depth :shock:

Go with the skinny, take advantage of having a light jeep.
 
Well....I raced it with the factory gears for awhile, and in 4-low it would fly for a 4 cylinder. If you add 100# of tires.....take 100# off your Jeep and forget about it. Weight is where it's at with the 4 cylinder, keep it light! You can run big tires fine, but you have to make compromises elsewhere.

It was a much better driving, although slightly slower for some reason, Jeep after I went to lower gears. The 4.56s still weren't quite enough to enjoy driving in fifth, but it was much better. Trail riding was more enjoyable too.

If you run deep mud, stay away from short skinny tires with aggressive tread patterns. They work great for general use or trail riding, but they will get you stuck quick in the deep stuff.
 

Go with a radial...it will roll easier. I have 36x14.50 TSL Raidials on mine with a 2.5L. 4.88 gears. it does fine.....have to hold a lower gear longer on some of the hills...but in 4 low...its a crawler!

Sorry :oops: I guess it does make a difference to witch size!

I have 4" BDS suspension lift and a 2 inch body lift with D44 rear with 4.88 loaded with ARB's front and rear! :p :shock:
 
You won't clear. I had a 4" Skyjacker, 3" BL, and lift shackles, and the 36s would eat the fenders up when I disconnected the front swaybar. Have you considered a set of TJ flares?

That's the narrow SS both me and Bounty referred to. It's taylor made for a light Jeep. Big pickups need those big balloons but a 4 banger YJ with those gnarly 27/32" lugs under her will rise to the occaision - and you won't have any problems stuffing the wheel wells with them either.
 
Now, correct me if I'm wrong guys, but aren't those among some of the heaviest tires around when you compare size to size? (not including the Boggers and Thornbirds)

If that's true..and understanding that many tires aren't made in the skinny configuration, why not go with lighter set of meats but with a bigger foot print?

Just throwing that out there, not sure if the weight thing is true or not, but I've heard so.
 

I don't know what they weigh but he mentioned Swampers at the start of the thread. A wider footprint is not necessarily an advantage depending on the vehicle and the terrain :wink:
