Seems a bit like one of those things where it depends on how militant the specific copper/force are being at the time. I think we're quite lucky here in Sussex, every time I've had need to interface with the boys in blue they've been a credit to the Force. Even when I got (rightly) pulled cos my MOT had run out... no defence, no excuses, it was a ****witted lapse on my behalf and I'd no problems with paying the fine; it was down to me, after all...the copper was good as gold, we even ended up chatting about bikes and stuff. He didn't treat me like scum for my idiocy or for driving a modified car, and he didn't go over the car with a fine tooth comb looking for whatever else he could find, though he'd have been within his rights given the legal unroadworthiness of the car. Didn't even care about the stick-on numberplate. Go to somewhere like Northants and the old Bill give Nazi camp guards a bad name; never encountered such pernicious, malevolent badly-adjusted excuses for human beings before. Their default setting is "I know I can do you for something, it's just a case of finding what it is" Really, it didn't oughta be like that It'd be even more annoying to get a pull for stretched tyres because I think it looks pretty whack but I couldn't get smaller than 265 without it looking stupid and any larger the arches would have needed pulling rather than just rolling.

How exactly would the Police 1. define 'stretch', and 2. measure the width of the rim? For 1. I'll assume they have from some supposed central tyre organisation, a list of tyres sizes, and the manufacturers' recommended rim width fitment. For 2. I'll assume they have an over-sized version of the below to so they can measure the width of the rim at the road-side. (The only other way is for a constable to crawl under your car to check the casting in the rear face, or ask you to remove the wheel so he can see it.) I can't see either of those happening, never mind both.

m sorry but a lot of cars ive seen with sretch you don't need no tools its blatantly obvious they're over stretched and I personally think its a good thing they're clamping down because ive always thought it dangerous for 2 reasons 1:- cornering stresses could easily pull it off the rim and 2:- on most cars if you have a flat the rim sits on the side wall so you can at least move to safety with no rim damage now if the tyres stretched you cannot do that

The Good = The Bad = The Ugly = Seriously, if your wheels won't fit without 10 degrees of camber & stupid amounts of stretch then they don't fit. I do agree that a slight amount of stretch to tuck the wheels nicely is ok, looks great and is relatively safe but trying to stick 185's on a 9J (extreme example) is dumb. This is an example of out local police deciding the rear tyres/wheels were not legal in Sheffield (pictures stolen from local forum, sorry Liam lol) As you can see they used the highly technical note book measurement approach, soon to adopted world wide.. maybe...

Do stretched tyres actually do anything for the handling, grip, braking etc or are they just a "look" ?

Subtle stretch can help reduce sidewall flex, which leads to more predictable break away and sliding. But beyond that, no. Excessive stretch causes the tyre to ride on the edges of the tread and reduces grip.

Actually reducing flex gives less predictable behaviour not more.
The edge of adhesion would be slightly further away, but god help you when you do reach it.
First hand experience from using the very same tyre in different sizes on the same wheels on a standard pug 205.

I don't believe the officers pictured here are even looking at tyre stretch, they are looking at wheel protrusion, since they appear to be 'measuring' how far the rim sticks out from the arch. C&U Regs allows 25mm of wheel protrusion, and this BMW doesn't look much, if any, more than that, so I'd be interested to hear which 'Law' they quoted when deeming the wheels 'illegal'.

I don't actually know, I was under the impresion it was for stretch and poke. I think Liam's on here though, so he may be able to clear it up.

OH MY GOD IT IS 6 YEARS AGO.... am I having a flash back? :lol: I dunno, I guess in my case it'll just a case of trial and error trying to get them on without huge amounts of stretch. The front wheels have come with a pair of 235/45/17s so it'll be handy to get these on the back. Cheers for everyone's input anyway Olie
