Stretch Tyres, Legal or illegal??

[AdamB]

for a stretched pic - see sig pic below

14x9 rear with 215/40/14 tyres.
Passed an MOT and had tyre re-fitted after a puncture.
Never had a problem with them from the law or garages.

shaft69 thats not stretched at all, do the maths..... 255mm's of tyre width works out at 10.039 inches, to me that means that the tyres sit perfectly over the 10 inch rim, or there may be .039 inches worth of stetch, about a tenth of a mm.

goddamn euro style.. 

as far as i'm aware theres no hard and fast law on stretched tires but like most things its at the discretion of who ever is inspecting it be it the MOT tester or the authoritahhhhs.

and yes having some stretched tyres will mean that there is a higher chance of breaking the bead when your hooning it around a corner - imagine how much the tire squidges down with just the weight of the car. now imagine how much it "squidges" when your doing 70 round a bend.  not saying DOOM DOOM IT WILL HAPPEN but theres a distinctly higher chance in my opinion.

usually ( and i say this in it's loosest form ) the cars with stretched tyre walls have the suspension to compensate for such forces through corners. I.E. Coilovers and ARBs.

I have just realised that I am going to sound all nerdy, but her goes...... slick as far as I was aware your suspension is only as good as the weakest link, therefore if you have uprated suspension (coil overs, thicker arbs, firmer bushes etc) then there will logically be more forces transmitted to the tyre side walls,and not the car. Therefore more flex in the sidewalls, as they will be the weakest part of your set up...I could be wrong, but it seems logical to me.

Whats MOT? we have DOT (Department Of Transportation) is it something like that?

[Optimus Wol]

MOT is ministry of transport. you have to have a MOT test done anually to show your car is of at least minimum quality to be on the road. you also need this certificate to tax your car and such. just thought i'd clue you up
