I'd say too much but obviously depends on the look you want. Saying that safety should come first as the jury is still out on the safety of tyre stretch full stop!!
As a point of comparison....i've got 8.5j to the front 215/35 and 9.5j rear, running 225/40. The tyres does look stretched but it is very low key. Looks more like well fitted tyres than anything else.
I share the same size combination as this, you must be running odd offset wheels/very low to need the additional mm's provided by this.
I would not be stretching a tyre that far and i'd be wary of if the fitter could get it on the rim, that would be a total pain to mount.
Was this aimed at me? I can't tell! Haha. Offsets about 30, but ill find out. As said, the stretch doesn't look mad at all. It looks well fitted campared to other stretched tyres. My stretch was easy to put on.
How does everyones insurers take stretched tyres?
Dealt with under 'aftermarket' wheels....but they didn't really care tbh. They told me they compare it to having different tyre makes so aren't fussed! Kinda strange but hey
Funny that, as mine classed going from an 88Y (which car came with from a VW dealer) to a 92Y (what the golf should be on) as a Mod...
Fit tyres that fit a wheel, I like to drive my cars...
Its funny really. I don't pay anymore for mine but seems you do? Wierd.
I like to drove my car to but not in the same way as I think you mean! I am careful even with my minor stretch. The jury is still out on whether stretch is safe or not. I've yet touch wood have had no problems. They are real low though! We'll see what happens.
Good luck and hopefully you won't kill some innocent person/people when your tyre delaminates/ruptures/explodes.
Don't wanna start an argument....but there is so ±ch out there about safe vs unsafe that I have no clue if they really ate unsafe or indeed they are safe. Yes if yiu have stupid stretch its potentially Sdangerous but so the research just isn't there!
