34x9.50"s on 15x8's???

I have the weak d35, but still have my 4.88's to install to out in someday. I have heard a lot of horror stories about running 35's on the d35. Would the Swamper 34x9.50 hurt the d35? And what do you guys think the 9.50 would look like on a 8" rim? I know that you can't air down with that, but I never do that anyway.

thinner tires are better for snow and paddling through mudd but they just dont give the badass look that the 12.5s give..

My buddy put some of those tires on his P/U and they road really rough, not sure if that makes a difference to you or not!

I'm running that tire in a 33" x 10.5" (on my stock D35) and I have no problems. I'm running the stock 15x8 rims.

I do not think 34" x 9.5" is much different interms of weight and should not be an issue. When I wear through the 33"s I have, the 34's will be next.

The main issue is gearing. I'm running 3.73's and they are really OK. However, 4.56 or 4.88 would be ideal to restore the acceleration.

I ran 33x12.50's locked on my D35 on my old TJ. But I had alloy shafts too. 33's are fine on a stock D35 if you arent rageing on it. So a narrow 34" like that probably weighs even less than a 33x12.50. Im sure you could run those without busting anything up as long as your smart. Remeber, bouncing breaks!

x2 - bouncing is not a good idea.... you need to pedal it and drive smart.

on the interco website, they suggest 15x7 rims. so would 15x8's be ok? i would like to think with the narrowness and light weight, they shouldnt hurt the gas mileage too much, not that it matters...

IMO - I do not think the 15x8's will cause any problems. You can call them directly or ask your local tire shop. You do not want a rim any wider than the width of the tire or a tire too wide for the rim.
If you're wondering about gas mileage...don't wonder anymore. The Jeep is a brick in the wind... The higher you go and more weight you add, just adds more drag coefficient.

34's on a d35? All depends on how you wheel it. Seen 31's snap a d35...seen 35's run fine on a d35. If you get in to it, you'll break it.

I think a buddy of mine is running that exact setup and he does fine. He takes it nice and easy and stays off the skinny pedal when wheeling it. His is a DD and he's had it forever with no breakage to speak of. He also does ok airing down. If I remember, those sidewalls are pretty stiff so he doesn't have problems with the beads.

Can you post a larger pic of your Jeep with this set up. Both the sizes you mentioned in your post are options I am considering. I'd like to see how it looks.

I attached a close-up as an atachment. Let's see if this works.

Specs: Super Swamper TSL Radials 33" x 10.5" on stock 15"x8" rims, no wheel spacers. I have since added JKS variable front coil adapters to level out the front end due to the extra weight.

The tires do not stick out beyond the stock fender flares.

MOz, those are the exact tires I had on my '01 (same color) with the stock wheels. I loved them. They rode and wore good. Low noise and smooth. I had 1" spacers on mine though. I would recommend the 10.50 radials on a 15x8 over the 9.50's. Interco makes a 34x10.50 in the LTB's. However, these are bias ply tires. Also, the manufacturers use a specific size wheel to get their specs such as diameter, section width, etc. Then they give you and approved wheel size range to go with that tire. I know, this is kind of an old thread but I had experience with this topic so I thought I'd chime in.....
