I have BFG 275/70/16 fitted to my 4WD. The left front has been leaking, going from 38psi to 25psi over the course of a week. The other 4 tyres ar OK with no problems.

I took it in for repair today (large franchise tyre dealer) and was told the case is faulty. It would appear they submerged the whole wheel under water and observed a number of "leaks" which they had circled using chalk or similar marker.

My question is whether this is a known fault and whether there is an easy fix. The leaks are on the tread pattern, not the sidewall. The tyre has 70% tread remaining. The serviceman said he had seen this before on one occasion in BFG.

Maybe a can of shooosh or whatever it is??

Been using BFG 245/70R16's for about 9 years now - not an issue of any sort with any of them - different size, probably different manufacturing plant (mine US), but it sounds suspect. Did you check the valve ? Valves and valve extraction tools are cheap - I usually carry spares.

You could put a tube in it I suppose. Keep it as a spare

If the tyre has a "number of leaks" it could be structurally compromised and potentially dangerous. Surely this is a warranty claim? Unless the tyre has been obviously abused I'd be trying to get a replacement at a significant discount.

Sorry to sound blunt, but if you where told the case is faulty by the dealer, get them to replace it. Easy fix!!

Agree! Its meant to hold air and it doesnt so its not fit for the purpose it was meant for!! Even if they made you pay half, it would make a good new spare.. Michael

Regardless of make, reputation, advertising, quality control etc a dud sometime gets through. Easy fix, buy a new one, probably not what you want to hear.
With 70% tread left ask for a prorata warranty, if you dont ask you wont get.
Several leaks around the tread mean you've either run over several small sharp items that have punctured the tread and carcass of the tyre or the tyre is starting to delaminate and air is escapeing through the delaminations. If it is delaminating it will fail fairly shortly.
Replace it now, they'll probably want it for inspection for you claim anyway.
Good luck

I would assume the tyre dealer would "know their stuff", but could it be a faulty wheel rim?

I had this problem once on the spare wheel of my trailer.
Because it laid flat on the drawbar, water sat around the edge of the rim and tyre and over time, rust developed, thus affecting the sealing properties.

I had a similar problem with small leaks on 2 tyres once - end result was that they had delaminated. They had suffered considerable abuse though. Sometimes delamination is a warranty issue, sometimes not, but I'd bite the bullet and replace it.

Sometimes it could be caused by a nail hole or fracture that has open hole on inside, and air is finding its way out through the inner casing showing up as very small leaks. Fixing the hole from inside should fix problem in most cases but not ALWAYS. Only way to fix is to remove and inspect repair properly.

Hi RalfR,

As a couple others suggested, the tyre must be replaced whether under warranty or if disallowed, by you. Am in the tyre business and this symptom certainly suggests a tread separation is occuring. If you have suffered a number of slight impact fractures through the tread rubber, the underlying steel belts may have been damaged and broken compromising the tyre's safety. This would not be warrantable, but if there are no impact fractures, then the case is at fault and should be an adjustable condition.

Take preferably to the retailer who sold you the tyres. If travelling, you need to talk to BFG/Michelin and ask their advice of a nearby dealer who can assist you.

Do not delay. This condition is potentially dangerous and advise prompt action.

Thanks all, I'm really not sure how I would go with warrantee as I did not purchase the tyres. The vehcile was purchased second hand and the BFG's were on it.

It won't hurt to ask at BFG though. The tyre is now a spare, but I think I'll replace it and kepp it as a spare spare.
