Outer Limits 4x4 Board

G'day folks, just a query, is anyone having trouble with xs weight required to balance their mudzillas. Mine in 33x13.5x15 going in for their 2nd balance from new, 3 balanced up ok but 1 required 410gm and another 390. Tyre service rang Maxxis and were told it's not a tyre issue just a problem that occurs with bias ply tyres. Is this pissing in my pocket or actually correct....Cheers Gaz

They have 2500km on them

I believe the Maxxis need to be on the reccommended rim width to achieve a good balance. Are yours on the right rim??
Also I can reccommend checking out www.autobalance.com as an alternative way to balance the "harder to balance" off road tyres.

I think your 13 1/2 inch wide tyre will need to be on a 10 inch rim to achieve a good balance. Check the recommended rim size placard on the tyre.

i have 35x13.5x15 maxxis mudzillers on 15x8 rims and there balanced great well as good as they can be

if your having them balanced make sure there warmed up to get rid of any flat spot from sitting as bias ply get

They do go a lot nicer on a 10" rim.

They use Nylon Cords in the Carcass of the Mudzilla which is a bit more prone to heat distortion. If you take the tyres for a solid drive and balance them hot, you'll get a far more accurate balance.

Thanks for the heads up on getting them hot before balancing, will give that a go. Also they are on 8" rims so as not to scrub so much on the front leaf springs at full lock.

Dont just add weights, actually turn the tyre on the rim to see if that brings it into balance that way.

Tried all that Mattlux69, tyre service spent 4 hours all up doing 5 tyres, 3 balanced with only 40gms was only 2 with the problem...

I have had bad tires before when in the bike shop that just wouldnt balance out at all. Sent them back for replacement, and the replacements were fine. So try the hot gig, but Im not sure it will be the cure if they spent 4 hours on it and were still talking to you

If you warm them up and balance them when warm, the weights will be added where they are required when warm. Does this change as the tyres cool down and will they stay balanced when cold?

i think the bias ply tyres get a memory as they are parked, so they hold the flat spot at the bottom of the tyre when parked for quite a bit of time.

takes a good drive to warm them up and remove this flat spot.

get some balancing sand from a truck mob worked alright in my mudzillas

hey gaz, darren had them on his gu, there crap, no grip and wouldnt balance

I have no experience with Maxxis, but lots with bias swampers. We used to balance them back in the day, and yes, they took heaps of lead to balance..... which would start coming off as soon as you started using them off road.. taking he balance out and they you were back where you started.

I haven't balanced an off road tyre for 8 years, and haven't had an issue, I pretty much end up running the best two on the front.

Autobalance would avoid the throwing weights problem.

because they are bias ply they can be extremely hard to balance i had 800 grams on one wheel for my creepy crawlers and rim was straight as no buckles in it its just the tyre bias ply's are absolutely awesome off road but not that great on road my 60 series jumped all over the road weith bias tyres on it then i switched back to radial and it drove straight as an arrow none the less bias are great off road also not that good in sand cause they dont bag

I almost guarantee if you took all the weights off they would have been no worse. The tyre isn't 800g out, but because wheel weights have to be added a long way from where the problem is (out at the tread) you have to add far more weight to compensate. also, 800g would have to be spread a long way around the rim, so it's a bad way of trying to fix a problem that might be confined to a small area of the tyre.

Powders like autobalance will obviously treat the problem where it is - out at the tread - so less material will me more effective.

Also - bias ply tyres work well in sand because the tread is flexible, not because they don't "bag" All my Bias tyres have bagged fine.

the only reason i didnt use balance bags because i couldnt get any through work at the time(used to work at the tyre factory for about 2 years) and didnt have any lead weights on them before hand and it shook like fawk so i had to use lead and it stopped 95% of the shaking , the balance bags arent that good from what i've heard from other shops is as soon as you get a bit of condensation inside the tyre the powder clumps up and causes the tyre to be inbalanced anyway so therefore acheiving nothing. i've heard this plenty of times, i had creepy crawlers had them down to 8 pound on the beach and the dunes and they dug like fawk no good on the sand

i heard the same thing about the powder. but have heard that they now have a silica based powder not so effected but moisture

The autobalance powder handles moisture ok and will not clump as stated previously.
