Time to come out of the closet

[Chris]

Very odd Dave. 40g here, 20g there, then one tyre was 400g. I said, whoa, let's turn that one. We did a refit at 180 degrees and it was still 400g. So we moved it to 890 degrees and it was still 400g. Basically this says, the wheel is perfect but the tyre is 400g out. They piled weights on and it cam out OK on the machine. But I made sure I stuck it on the back. I will give it a whirl but if there's any vibration then I shall just stick a litre of OKO in each tyre and be done with it. It's worked every time for over 20 years.

I'm sure you know of this anyway Chris but, when I put my at's back on the car on the original alloys I pulled off just to check everything was OK ( been playing with the brakes) and there was a scraping noise. Turned out it was double thickness wheel weights on one of the alloys on the rear rubbing the brake back plate thingy. Swapped it for a wheel from the front that had less weights and all good. Just mentioning it incase it happens to you.

on the OKO's

 

[Chris]

Yes, Nick you're correct. I am on that. Just one wheel and we placed the weights out of harm's way.

If the tyres are stored for a long time they can deform and need lots of weights to make them "round" again. Trouble is when they get hot they reform and start to vibrate. Hope that isn't the case Chris.

I think Frank, if you use OKO tyre sealant and the tyre changes it will compensate and keep it in balance.

 

[Chris]

Sorry Frank, but I don't buy that. Sounds like complete rubbish to me. Deform? Really? That would mean that new tyres stored in garages would have a shelf life that would put tyre fitters out of business. These are extremely strong tyres with side walls you can barely deform if you try. A couple of years in a shed isn't going to make them square. As Chas said, the OKO is a dynamic balancing material. Doesn't matter what the deformity, OKO will sort it. I have balanced 37" muds with OKO before. 3 of them only needed between 20 and 40g. Very odd that one needed 400g I agree, but whatever 'shape' the tyre might take on, the mass can't change. and neither can the material composition of the rubber. I suspect that this was mounted on a wheel previously that might have led to the imbalance and now fitted to a 'perfect' wheel is showing the wear pattern.

Are you thinking of the flat spots tyres can sometimes develop when vehicles are long term stored without raising the wheels off the ground Frank? An "out of round" tyre may give similar symptoms to a weight imbalance but obviously require different cures. A problem much more acute on a motorcycle when it happens.

 

[frank rabbets]

No TP. I've had flat spots on stored car tyres before especially with cross plies with hard walls. This creates a different kind of "judder" than out of balance which is more of a vibration. After a few miles and the tyres had heated up I never had a tyre that did not recover.

Tyres in storage must be rotated every 4 weeks to avoid deformation. Not my rubbish but directly from the tyre makers themselves.

 

[Gary820]

I think it's a wheel problem Chris, obviously they're not fit for purpose. I'll come over and take them off your hands, for disposal of course

 

[frank rabbets]

You might be safe Gary but refurbed wheels need double checking on a spinned hub before tyres are fitted. Don't care who's done them. Tyres after long term storage need running/getting warm for 50 miles before balancing. Don't care who's stored them.

 

[Chris]

Thanks Gary, would you?

 

[Gary820]

Thanks Gary, would you?

Yeah I'll pop over. The sooner those wheels are safely fitted to mine erm I mean safely disposed of for elf and safety reasons the better

I love the Toyota OE wheels, I recall seeing a test video of how the Japanese test alloy wheels, it was quite impressive what damage the OE wheels can tolerate.

Re the tyres and storage. Unsure if this is heat related or not but, tyres dealers in Spain do not keep tyres for more than a few weeks in fact, pretty much every tyre not on the ultra common list has to be ordered. We know the tyres are dated and most Spanish will not purchase a tyre that is not or very close to the current year. I had never heard about this until getting my business started.

Re the Toyo tyres (Open Country), I think they are great until they get three - four years on them, again may be sun related but mine started getting punctures in them when there was still 4mm of tread, they were almost dissolving in front of me. The punctures were not side wall as per the Tabernas trip (different brand) but directly through the tread pattern, a bolt, a couple of screws, and a piece of unidentifiable metal. I too had some trouble getting a couple balanced, I went for the rear fit option and the stick on weights just clipped the rear calliper, a small bend on the pad retainer and all was good.

On the refurbishment of wheels, I tried to get mine refurbished in Spain and the guy tried to rip me off. The price went from around 40 euros each to 70+! I spoke to a 4x4 club member and he had a transport company pick them up, refurbish them, paint, lacquer and then transport them back to me for 200 euros all in.........from Portugal, go figure!

As I said, I'll just stick OKO in them and be done. This isn't going to be doing many miles and I simply need some large black rubber washers to stand it on to keep it off the ground.

Dave the tyre makers say to rotate tyres every 4 weeks to prevent distortion presumably through gravity. That's for UK as well. You can balance a distorted tyre but when it retains it's original shape after getting hot it needs balancing again. It doesn't always happen but CAN happen with any tyre. Some people think this is rubbish, I suspect Quick fit included, I doubt whether they've ever heard of such a thing.
