Seriously? Would you trust a car knowing thats how the tyres had been put on?

'ere we go again.

I know people moan and bleat about stretched tyres, but has there been any recorded accidents where a stretched tyre has been the main cause or a major factor that would have meant a different outcome to an event?

I'm with you - I just don't get it. Anyone who does that has probably done lots of other stuff that would have screwed the car up anyway with lowered stiffened suspension, "racing brakes" etc which I can at least see the point of but stretched tyres?

I'd rather go with the tyre manufacturers opinion, this is from Toyo

"Serious personal injury or death can result from failure to select the proper tire and rim: Tire MUST match the width and diameter requirements of the rim. When mounting truck type radial tires use only wheels approved for radial tires.

NEVER put flammable substances in tire/rim assemblies at any time. Never put any flammable substance into a tire/rim assembly and attempt to ignite to seat the beads.

NOTE TO PROFESSIONAL TIRE INSTALLERS: Exceeding the maximum bead seating pressure — The tire service person must NEVER INFLATE BEYOND 40 POUNDS PRESSURE TO SEAT BEADS unless specified by the tire manufacturer! "


A quick google, and a couple of people have had the tyre come off the rim, one at 90 on a motorway...after someone says.....

"If stretched tyres are soo dangerous why hasnt there been a single person on e38 whos had a problem? I've never seen a thread saying 'My tyre fell off' "

But that was a 195 tyre on a 7.5" rim and as a later poster says "195 on a 7.5 is hardly a stretch, either the tyre pressure was too low or a bad tyre in the first place id say".

My Westfield is a 185 tyre on a 7" rim, there's no stretch at all. Granted the wheel size is a little different, not sure how much difference that would make. Pic is in my profile.

Should it be banned?

Before you answer lets expand the question to.

How would it be banned?

By making it so all cars have to go through a very strict test annually instead of an MOT that ensures the car is to exactly manufacturers spec

So should all modifications to cars be banned?

I'd rather they weren't

I'm far more likely to be killed by a crap driver then a stretched tyre or any other mod

If you want stretched tyres banned then do please feel free to join brake

The rough guide is the rim should be 90% of the tyre width with a 1/2in leeway either side.
For a 185mm wide tyre that makes the ideal rim 6.5in but 6in or 7in should be fine.
For a 195mm wide tyre that makes the ideal rim 7in (6.9in) so 6.5in or 7.5in should also be fine.
Obviously check with tyre manufacturers for their specific recommendations.

I'm a great supporter of rimming and say it shouldn't be banned. What people do in the privacy of their own homes is up to them. Just don't try kissing me afterwards!

Oh sorry - wrong forum! Different kind of rimming!

There will be a new section on the MOT test introduced, entitled 'Innapropriate Repairs and Modifications'

This may be used as a catch all for anything that in the testers opinion is dangerous, hopefully the tester will take advice from VOSA to justify a fail.

I think it primarily happened due to people wanting to put a deep dish wheel on a car, which in turn required the stretching of the tyre to fit under the arch and stay within legal constraints.

Not really a fan of the 'full on' look myself either. smile

Not exactly, more for the tread to fit under the arch. Putting on a normal low profile tyre the tread will more than likely stick out with a wide rim wink

I think if you had a big accident which included a deflated tyre, the insurance company might well try and hold you liable.
By deliberately contradicting all the guidence when fitting a key item of safety, I think most courts would argue you are responsible for any issues. I certainly would.
