Wantted mt tires

[Dakota Rigs]

I need some my tires for when I lift my truck. I need at least 31x10.50 r15 but I will take a 33 or 35 must be 15 in rim

How is your truck geared? Gearing and tire size are critical for maintaining any kind of performance in your vehicle. If you are not planning or have not regeared your axles, you may not want 33's and probably won't want 35's.

I have a 4.10 gearing the stock gearing for my truck

I went from the stock 235/75/15/ to 31x10.50x15 on the stock 3.73 gears. MAJOR difference in performance. Hasn't hurt me on the trails much although I do wish it was geared lower. I'm leaving it as is for now because I plan to go bigger and will re-gear at that time. You will notice a difference in power even going to a 31" tire if your still stock.

Well do you think I can fit 31s on stock height? And I have done a couple things to the engine. I'm putting a chip soon

On my Explorer I have 35's and put in 4:88's (wish I would have went with the 5:13's, but everybody was out when I did the gear swap). It put me back to almost stock ratio. In my Ranger I only have 4:56's and 36's, but I have a high HP engine (v-8) and will eventually gear the transfer case (Dana 20). Dont have a clue on how close the ratio is on the Ranger, as everything is changed from stock (engine, transmission, T-case, axles). It take a bit to get big rubber moving.

I have a set of 31x10.5xr15 BFG KM2. Lot of tread left (about 13/32") but have seen plenty of trail and show it.


I have a 5th tire also but is not same shape or brand, will throw it in too. They have been setting unused in the garage for a while. Send me a PM if you are interested.

4.10 should be fine for 31s. I believe I heard it here but 4.10 has the optimal gear ratio for low gearing and gear size. At 4.10 the ring and pinion gear are as large and strong as they can get while having a relatively low ratio. Once you hit 4.56 the pinion gear has to be smaller to account for the larger ring gear. This means less contact between the two gears and if you get to throttle happy you could shear the pinion gear up. It may be another ratio but i'm pretty certain it's 4.10. Regardless keep in mind the lower you go in gears the more careful you should be slamming the skinny pedal.

Back on topic I agree with everyone else just go with 31s for the time being. Good all around size in my opinion. Good on and off road and doesn't look massive on your truck if you aren't into that look.

what size tires are on it now?

Those would be ~29". People say with my truck you can fit 31s under but in all reality they will rub and will get chewed up or screw up the fenders on a trail. If it looks like there is some clearance from the top of your tire to your fender then I'd say go for it. You can always cut or buy longer bumpstops. You could even flex one side completely out and measure how much clearance is left. If there is ~1" then you should be fairly good but close, more then an inch would be optimal for going from 29s to 31s

Oh and I have no bump stops as they fell off

[96EXXLTinCO]

In pic #2 it looks like your rear tire is awfully close to rubbing at the front. As Dante said, you could always put em on and run one tire up on a ramp or something and if they're going to get into a fender, then either get a lift or lower bumpstops. It's pretty hard to tell just from pics what your workin with there exactly, but it definitely looks a little tight in the rear. If it was me, I would put em on and flex it and get some bumpstops on there that are low enough to keep em out of the fenders.

If I remember right the front of the rear tire is actually further away from the fender then the rear of the rear tire

I have 35s

[ColoJeeper]

In my JKU, I am running 35's with 4.10 gearing and a 6 speed manual transmission. Off-road it does great as I have the 4.1 tranfer case, but on the road, performance wise it is a dog. I would not be happy with it if this were my daily driver and not just a toy. My plan in the future is to go with 5.13 gears to bring the on-street performance back to stock or slightly better.

There is all the measurements I could get what do you guys think about the change from 29.5inches to about 30.7inches?
