Just wondering how much weight it took to balance your 35x12.50 R17 toyos. I just picked mine up from discount and four of them had and average of 4 oz. and one did not require any. i called and thought maybe the weights fell off of this one but the guy said he checked twice and it did not ask for extra weight. does this sound right?

 

sounds right, although its not common for a mudder to not take weight it is possible, especially if they did a road force balance, thish matches the inbalance of the rim opposite the imbalance of the tire to counteract one another. there are times when it allows for not needing any weights. If it doesn't shake, wobble, or shimmy on the freeway, then you're balance is fine. I however have a set of dick cepek mud countrys in the same size that are just about impossible to balance. I have 12 oz of internal media balancing, 6 oz on the inside of the rim, 4 more on the outside of the rim on one of the wheels and its still not a perfect zero. So if you're not having any vibration issues, then your balance is fine.

 

thanks. i haven't mounted them yet, it doesn't get lifted till saturday.

 

3 to 4 oz for a 35 MT is pretty good. I just sold my 35s Toyo Open Country MT to Toad and they only took 1.75 oz per tire and got a perfect 0 balance... My 33s Pro Comp Xtreme MT took about 3 to 4 oz each and didn't balance out perfectly.

 

Damn, I'd be returning that tire!

Hey jeeper, didja' ever get your electric windows done? We corresponded about the cable drive systems from Ebay a while back...months ago, actually!

Mine are actually working really well. Very happy with 'em!!

 

I'd also check to see if your rim is bent.

 

my 37s did not take much maybe 1.75 - 2.25 to balance out

 

ok, not trying to dictate just help. i have been doing medium truck (tractor trailer) tires for the past 7 years. the bigger the tire the more the weight it is going to take. also it depends on what kind of balance they did. there are 2 types in essential (although were the weights go can very, but there is only 2 types) those are dynamic and static. dynamic balance has weight on both sides of the rim and is a much better balance then static. static balance has weights only to the inside of the rim or maybe on the drop center (it is done for estetic reasons usually) both balances are good balances. there is also a powder balance. where a predetermined amount of media (like sand but NOT) is used inside the tire. this is also a good balance. both have pros and cons. the media balance is always changing with the tire wear as it moves around. the con is it can get stuck in the valve core and leak. there are special cores with filters on but they still leak as well. when checking tire pressures you MUST put a little air back in to clear the stem. the spin balance pros are they are more accurate (by now most shops should have computer balancers). the con is as the tire develops a wear pattern the balance changes! you will never get around this. a good tire shop should rebalance tires with rotations. this is the only way of taking care of that problem. NEVER USE THE TWO TOGETHER!!! they were not designed to use together and you are just adding more weight. the other problem is when you have joe bob tire balance them is make sure they do it right. makes sure there is never any weights directly across from each other, this is a counter balance and one weight is just canceling out the other. this only goes for one side of the rim at a time. also they should check radial runout the roundness of the tire and the lateral runout, the side to side shake. all tires should have a spec. you would be surprised on how bad this is sometimes with new wheels and tires. goodyear is the worst for this. also there is sometimes dots on the tires. the yellow or white dot should go to the valve. this is the lightest part of the tire. the green dot means it was xrayed, and the red dot usually means the same thing.

in short i would have no problem sending a 35x12.50r17 out the door with 8 oz. of weight on each wheel. i have seen smaller tires go with more (because the owner was cheap and wouldn t replace a bent rim). big truck tires go out the door usually with about 10 to 15 oz of weight. i d have to check but the media balance is probably 5 to 6 oz. of powder. and yes once in ablue moon a tire might not take any weight.

 

great response greasemonkey85. If you use a spin balancer, while the wheel is spinning, you can look and see if the wheel is hopping. (if the hood is down it is hard too see this) If the wheel/tire is moving up and down, no matter the balance, you can get a vibration. The more pronounced this hop the more you will feel it when driving. The side to side motion generally will not cause a vibration, but if bad enough it will cause irregular tire wear.
I would question any 35 inch tire that didn't take a little bit of weight, even if it is a Toyo. (which by the way balance very well)

 

exactly.... the up and down hop is the radial runout. on tractor trailer steers we use a dial indicator and check this. the spec is .05, if it is more than this it should be changed. then to take it one step farther we take the high spot and put it to the top on the hub, THEN tighten the lugs. the difference is suppost to even out for the drop on the hub. penkse truck leasing.... this is all they do as far as balance hence they don t spin balance tires. very good system.
