Hi all,

On way to work yesterday, i noticed my tyre was flat so changed it at side of road.

Went to local garage to get it looked at. When he filled it with air, the sidewalls on two places had bulged.

I've got a spare to replace it with, but wondering if it would be safe to reuse in future?

Cheers

Matt

 

BIN, NOW!!!

 

agree with Ian as most tyre walls crumble after driving a few metres so any sign of a bulge its dead

 

no way! toss it. its just the way it goes, tough luck if it had lots of tread!

 

do you think the tyre will repair itself over time and the bulges go away?

the tyre is scrap, once its been run flat, or even left flat with the weight of the car on it for a length of time, the side walls will be damaged, and could blow out if inflated and used.

 

Cheers for all the replies. Assumed that wud be the case. Just bit gutting its got loads of tread left on it.

Cheers

 

Many moons ago i had an MG Metro turbo (the ones with the 6r4 shell ) i used to drive it really hard, one day i was scraping the door handles off the car (just an expression, the door handles don't actually get scraped) on a roundabout (it handled like a go-kart) when a big truck cut me up/ changed lanes and blocked me off - i had no where to go exept to batter into the kerb (at high speed) there was no suspension damage, the tyre stayed up but there was 2 (inside and outside) big bulges in the tyre, and 2 small dents in the rim, when i went to replace the tyre i discovered that the MG Metro turbo has special tyres made for it by one manufacturer - hard to get/ must pay full price etc

So i kept running it like that for a year or so, / or untill the tyre wore out, continuing to drive very hard with no problems (untill i blow the engine up)

Im older and wiser now, and i would remember which corner i put the tyre back on so that i would be ready when the car spins off backwards, (on the rear) or understeers straight on (on the front) if (when) the tyre explodes (just kidding - tyres are an important safety issue)

Unscrupulous dealers would turn the tyres round till the bulje was on the inside, Its an MOT failure and dangerous, i don't even think you could (or could not advise you to) use it as an emergency "get you home" spare untill you replaced it next payday etc or to fill up the space in the spare wheel well, if you sold the car with it as a spare you should inform the buyer it has bulges or needs to be replaced.

The 4 litte contact patches of rubber are often underestimated by many drivers (pressure/ condition etc) but its all there is between you and the road

Up until recently, tyres never really bothered me - I knew some were grippier than others, but other than that I didn't have a clue about all the other specs on them - load bearing, speed ratings, etc. Just things that had never entered my mind - I'd looked at speed ratings as "well I'm not gonna be doing 149mph, so I don't need V rated tyres", but then you realise that the higher the speed rating, the better the tyre is constructed, which affects it's quality at any speed, not just maximum. Same with load - sure, I could get an 89 rated tyre, which will support 580kgs (and my car exerts about 526kgs per tyre) - but then you realise that a higher load rated tyre, such as a 93, will handle the weight, fully laden or not, at any speed better than a lower load rated tyre.

So even if you aren't gonna be driving the doors off it, a 93V is going to be all round better than an 89H.

I can't afford the absolute last name in tyres, but I will now always go for the best I can afford, rather than look for the most affordable. I'd rather spend double on tyres and nothing on engine mods, than spend £x on making it faster and buying lesser tyres.
