With all the talk of 35's or 37's being the Max. reliable tire size for D30's/D44's, I thought others might find my findings interesting; probably not, but I did :)

315/75 R16 (35X12.50) MT/R on MT wheel W/ Champion beadlock = 85lbs.
37X12.50 R17 MT/R on MT wheel W/Champion beadlock = 111lbs.

It'd be cool if someone had a stock tire laying around on the rim to weigh that as well. Thanks Paul! :wave:

Wow 104 pounds more for a set. I need to start finding stuff in the jeep to do without.

130lbs including a spare!!! Seriously, I need to take another look at what I can do without if I'm going to run 37's.

I'll post the weight of a 37X12.50 R15 MT/R in a day or two. There may be a difference between the different load ratings.

35x12.50r15 MTR, 70% tread, on 15x10 steel wheel with 5 golf-balls inside = 92 pounds

same MTR unmounted = 57 pounds (therefore 15x10 steel wheel = 35)

33x12.50r15 BFG LongTrail (very similar to AT) on 15x8 steel wheel = 69 pounds

Paul, I have an idea, how about getting rid of the driver!

You're about 130 aren't you?

Just walk beside it and steer it from there. You don't need the throttle with a stick!

if this thread goes away from tire weights and onto other weights and losing weight, we could just revive this thread: http://www.naxja.org/forum/showthread.php?t=44176

A few numbers
front axle shaft with u-joint short side 12
long side 19

spare steering 13.5
spare drive shaft 18
sun visor(set) 3
mastercraft seat with base 37

I'm looking into shaving weight from the tool box. I have to many tools with me.

This is why I'm trying to loose weight, If I just go without food the next three weeks, my jeep will be able to handle the added weight of bigger tires. This will also save me hundreds of dollars (I eat alot) and buying those new tires will be a sinch!!

internal balance. some people use BBs, or Equal, I'm having pretty good luck with golf-balls.

Currently Ive got BFG 30x9 I'll give them a weigh in tomorrow (although you guys are probably more interested in the bigger tires)

How heavy are the 17" Champion beadlocks? Walker Evans are something like 45 lbs. each. :scared: Those are some heavy rollers!

I know both come into play here , but doesn't the larger diameter/leverage have more of an effect on breaking axles compared to the actual weight of the wheel/tire?

both will apply. the larger the radius, the more leverage it will have on the shafts. kinda like having a 37" cheater bar vs. a 35" cheater bar.

I understand that, I'm just assuming that of the two factors involved, the tires diameter has more to do with axles snapping then the wheel/tires weight.

Tried Equal, but it clumps if you air up and down often.
Do the golf balls take a bit to get the tire balanced? With the Equal, I found that the tire would shake briefly until everything evened out.

And 32-10.5 TSL radials 50% and heavily grooved on a 15x8 OEM 5 hole weigh 60lbs. My spare w/ @1000 miles weighs 70lbs.

And I'll revive that other thread.

i heard what i think is a really good idea the other day, but it might get expensive, I haven't checked prices. Airsoft pellets!

I saw something recently about some sort of composite or ceramic beads, can't remember.

yeah, i haven't checked the price on the ceramic beads. if the airsoft pellets are cheap enough in bulk, I would do those.

I have some Truxus MTs in 265/75R15 and BFG MT (not KM) in 35x12.5x15 (unmounted) in the barn. Also have some bare ARE-767 (15x8) as well.

I'll weigh them and post tomorrow. I'm too lazy currently and it's raining here. Gives me an excuse to pick up a "garage scale" while in the city tomorrow instead of lugging the wife's bathroom scale out there. LOL

One of the guys in my club swears by this stuff (brand name specific - can be gotten at most truck stops apparently):

He uses it on the 35s on his TLC FJ70.

I'm going to give it a go with my new Truxuseses (Truxi?).

golf balls work, only complaint I had was when stopping and my passenger always asked "what was that?" as they hit off the inside of the wheel.

i have never heard them hitting the wheel, on road or off. sometimes at low speed you can hear them rolling in the bottom.

same MTR unmounted = 57 pounds (therefore 15x10 steel wheel = 35)

33x12.50r15 BFG LongTrail (very similar to AT) on 15x8 steel wheel = 69 pounds

I just weighed an unmounted 315/75R16 with 95% tread, 62lbs. So basically the same weight between C load & D load ratings.
16X8 Campion beadlock is therefore 23lbs.

37X12.50R16 Creepy Crawler on a Champion beadlock, 105lbs.

I'm using the same wheels for weights, MT Classic 2's W/Champions, the only difference is the size. I'm sure they weigh about the same.

The larger diameter probably has much more effect on breakage than the weight, but the weight difference is way more significant than I would have thought.

OK, I understand the reduction of weight up above, but tires? Why worry about the extra hundred pounds due to the increase in tire size? :confused:

Every pound counts.

Every pound counts.
To offset the engine strain? I figured that extra weight in tires might be good as it's low to the ground and it keeps the CG down. Come on... details, I'm really curious.

BrettM
April 1st, 2005, 06:56
like he said, every pound counts. you are correct, if you must have weight, it is better to have it low, but it is better to just not have it at all.

Well but isn't there a point where you loose traction due to LACK of any substantial weight?

no. you will have less traction, but you will also have less weight to move and therefore less force needed. lightweight is good. low weight is good. I really can't imagine a scenario where you could have too much of either.

I can run any speed smoothly with my unbalanced MT/R's on Champion beadlocks. :) :)

Thankfully, I've never had to balance them, both 35's and 37's.

Ludakris
April 1st, 2005, 11:18
both will apply. the larger the radius, the more leverage it will have on the shafts. kinda like having a 37" cheater bar vs. a 35" cheater bar.

then throw in "rotating mass".... the extra weight, centrificul (sp?) force is greater.. as is the torque which it applies..mmmmm, physics....

Finally got the numbers and the sky has cleared enough for a sat connection:

Interco Truxus MT 265/75R16 (32" x 10.5" x 16") :: 56 lb

BFGoodrich Mud Terrain (old style, 50%) 35" x 12.5" x 15" :: 52 lb

American Racing ARE-767 15" x 8" 4" BS :: 28 lb

All measurements are taken with a bathroom scale - I'd assume at least a half pound error in the numbers.

I'm not sure which tire is lacking. Is the Truxus really heavy for it's size or is the old style BFG way underweight?

I am really surprised at the weight of the Truxus. I was putting off the WJ brake upgrade but I think with a wieght like that it may become a priority (my Jeep is a DD).
