Someone at work has a car fitted with large alloys and very low profile tyres and the subject of kerbing them came up the other night, he has recently clipped a kerb for the first time with them.
Now, he says that the tyres he has fitted have some sort of design to try and save the alloys to a limited extent from kerbing, he has Hankooks on the wheels so nothing extra special really but says that they have something he called Tyre ave or Tyresaver on them whereby they sort of overlap the rim of the wheel slightly so that if it just nudges into a kerb it's the tyre and not the rim that takes the damage.
Has anyone else heard of this type of tyre design before, he says that it only really applies to low profile tyres but that it's pretty standard.
Has anyone else come across thhis design before and is it much good? Sorry to be a bit vague in the description!

Yes, I,ve seen them. Not a bad idea on the surface but it really depends upon how hard the alloy is kerbed.

Yes, the (excellent) Goodyear Eagle GSD3 F1 tyres that I have just fitted to my V70 2.4T have rim protectors. These are effectively a heavily reinforced band located a few millimetres away from, and standing prouder than, the wheel rim. The band is located under the outer rubber skin of the sidewall, so is a fully integrated part of the design.
I wish I'd had them when the car was brand new (Pirelli P6000), because as any S60/V70/S80 driver will know, where the wider tyre options are fitted these vehicles assume the turning circle of an oil supertanker with a broken rudder; pulling out of a side road in to a main road that I had done countless times before with other cars, I scraped my front lefthand wheel down a very jagged kerb because I ran out of lock. Heavy traffic had closed my route behind preventing making a three-pointer of the manoeuvre.

I have Dunlop SP9000s on my Volvo S40, and they use a similar sort of design. Dunlop rather grandly call it the 'MFS system' (maximum flange shield). As mjm says, it will protect them to a certain extent (eg. from a 'sliding' contact with a kerb at a narrow angle), but if you really misjudge things and hit a kerb from a greater angle you'll still take lumps out of your rim. As SjB says, Pirelli P6000s offer no such protection whatsoever (and aren't much good anyway IMO).

Very good, I like the sound of those sort of tyres then, will make sure that they get fitted when I next need to change, especailly if I get the Focus Sport as it has particularly vulnerable alloys.
Thanks everyone.

The continental contisport contacts on the goona have them, kinda thick ridge. None of the the alloys is marked in 40k miles.
