36-37 inch tires

[CliftonRover]

I have narrowed down my search for a 36 to 37 inch tire for my classic rangie that will be used primarily for offroading. I will be able to trailer it long distances. Sumper swamper is the only company that makes tires this size in my price range. My choices are:
bias TSL 13x36x16 for $207.43
TSL radial 36x12.5 R16, for $235.53
TSL/SX 36x12.5 R16, for $238.09
IROK bias 36x13.5x16 for $216.98

I know these are big and they are alot of tire for a rover but I am only going to be wheeling with it and driving it in less that 30 minute trips to local trail heads. The 13.5 wide IROKS's looked a similar with to the 37x12.5 wide goodyear MTR's which surprised me. I really like the IROK but if anyone has suggestions please let me know.

My only real suggestion is enjoy it, I know a few RRC's with that size tire, they do fine, but they have had to upgrade axles and such for a precautionary measure!

I've only ever heard and seen good things about the TSLs. Most of the trucks I wheel with run them.

As a side note, I wanted to get 35"+ tires for my Rover and decided to stick to 33"s for now... I regret it soooo much now, I could easily run some bigger ones in there. Oh well, next summer I guess.

As far as bias ply vs. radial ply, if you're gonna mostly trailer your truck around it doesn't make too much difference. Otherwise, radials that big will be eaten by pavement in no time.

Can't wait to see your truck with those boots mounted on

Interco is releasing a 35" LTB bias in April, it should be a lot cheaper than those prices. Q-78s are a great rover size too, they fit rover wheels and tuck well, 35.5 tall by 11 or so.

What type of wheeling conditions are you going to be encountering? What do you plan on doing with the truck? What body or chassis mods are you planning for the future? Questions that need to be answered before you decide on tire size and make. More information, will lead to better answers and help you save money down the road. Oh yeah, question number one which needs to be answered before the others regarding your above choices; What wheels are you planning on using???

[CliftonRover]

I will have 2" spacers, rovertym 3 inch springs and i will cut the fenders.
I will run unlocked at first, with disco diffs with 4.70's, and rovertracks axles front and rear. I have 34's now with OME HD's and 2 inch spacers and they fit fine. I will either make a 4 link for the front of just adjust my radius arms. I have rovertym trailing arms for a 5" lift. In time I will get high angle drive shafts. I do not do a lot of slick rock as I live in New England but I do more mud,snow, roots/ heavily wooded trails. I have heard that the rovertym 3' springs are more like 4"

[CliftonRover]

as far as wheels I am not really sure, I have 110 wheels as an option if they are any wider. I have a bunch of rover 15" rims but they are too narrow, and I have the rrc alloys which I have heard hold a bead the best. could I run the bias 13" wide tire on a rrc alloy? I feel like bias would not mind this as much as a radial?

[XtremeMarine]

You can't even run a 12" safely on a stock RRC alloy. Your best bet would be to buy a set of wolf steelies from RoversNorth in Vt. Then get a weld on, do it yourself beadlock kit, and have a competent welder install them. Then you can run 12-12.5's. For thirteens, you are going to have to get custom made aftermarket wheels, and most likely beadlocks, for safety. For mud in New England, I would rather have tall and skinny. I would go with the tires KevinNY suggested, or a 35-36, x 10.5-11.5 on a 8" wide rim. Then beadlock would be optional for performance, instead of mandatory for safety. Also , remember that a narrow tire will stuff easier at full articulation, and require much less cutting of the wheelwells.

[XtremeMarine]

As an example, on my Series IIa, the wheel/tire set up is as follows. 16"x6" Series wheels. Weld-on beadlocks from StraightForward Suppliers, which give me a working width of 7.5", Interco Boggers, 35x10.5x16. Tire is only 3" wider than wheel, so no safety issue, and no need for an internal, or inside rim beadlock.

For your suspension set-up, and lift; 35's or 36's won't be an issue. Articulation and steering will be. 12 and 12.5's seem to be the max on these rigs without serious turning issues. At 13 or wider, you will need to look at hydraulic assist in your steering, something like a rock ram set-up. And to turn those meats while stuffed, it would be simpler to remove the fender completely.

[CliftonRover]

Thanks I will go with the 12.5's on wolf wheels and I am a competent of enough fabricator to put the weld on bead locks on. I will be bolting on disco axle housings and internals because I currently have the 10 spline crap. Can I switch the calipers from the rangie to these axles or should I count on finding housings with good calipers? Then I will get the springs and tires. I should be fine with the stock disco axles for a SHORT time. my 34's havent snapped a 10 spline yet, but I know not to spin them in the air.

[CliftonRover]

how tall are the new LTB's really going to be?

[XtremeMarine]

Go to the interco website, they have a great sizing chart available for all models. Can't give you the link, sorry, it's in my laptop, not my work computer. Easy to find though.

[XtremeMarine]

Remember to tank test your wheels for leaks after installing your beadlocks. I'm pretty good to very good with a mig, and I still found leaks on 4 out of 6 of mine. After grinding off the rough edges of course. Probably wasn't my welding, but my over-aggressive grinding. LOL!

[XtremeMarine]

What year is your RRC? If you're going to swap entire axle housings, I'd recommend going for 98-99 DI axles so you'd have the most up to date brakes. But I'm not sure if those are direct drop in fit to an RRC. Why don't you just try to find 94-95 RRC axles instead?

[CliftonRover]

my classic is an 89, I have just been able to find disco axles more easily than rrc ones. I just put 97 disco axles under my 200 tdi 109 station wagon. they are pretty bomb proof in that application.
