Seems to me that Goodyears should be ok if they are XL / over 87 rated and used with high tyre pressures.
But then, I'm not sure it's worth risking the excess wear when the Toyos and Michelins are just about as good in the wet and don't seem to have these problems.
The garage I was talking about sits near our local Subaru dealership and many Scooby owners use it. The Garage owner has spoken to a lot of Scooby owners, I've used him a few times with other cars and he seems a genuine bloke.
Still, I'm interested to hear anyone else's thoughts on this before I make a final decision (Scoobynet is awesome for this kind of problem !).

That would be convenient, since it would suggest there's nothing wrong with their tyres ! Maybe the 4wd is a bit rough on the soft F1 tyrewalls and this causes the wear ?

Maybe, and it is convenient for them. But being honest, it is a fact that sidewall failure and outside edge wear is a sign of an underinflated tyre. Also shock loading from large potholes or kurbs.
Moreso if the tyre is used in high speed and/or heavy cornering excercises. Which may call for higher tyre pressures to compensate.
With concern if amount of driven wheels can play a factor in this, from what I have gathered, it is the opposite. Where cars that wheelspin are more likely to suffer internal tyre failure (very different to sidewall splitting). As 4wd generally doesn't make much difference to lateral grip or loading on a tyre which is what forces a tyre to roll onto its sidewall.
All I can say is there are people who have had 83 rated GSD3 on newage scoobs who have not suffered failure, whilst others have. The only other things to account for this is: driving style, pressures used whilst driving in that manner, maintanance of pressures and observation of condition, suspension geometry variations and batch variations. It has also noted similar failures on other brands of tyre.
Which is why I find it difficult to draw a valid conclusion to the issue. So only give benefit of doubt and assuming that the driver will drive enthusiastically rather than within the limits of the law, with little understanding of how tyres pressures affect a tyres contact path under loading, it maybe wiser to opt for the 87 load rated tyre.
Perhaps we should draw Shaun/SDB into this, seeing he aledges to know something about tyres (re: his tyre articles)

Yes and no. In a typecast scienario where a tyre sidewall failed because of overloading, overspeed or underinflation. Wear on the outer edges would also be noted.
This also goes hand in hand with chucking round bends, driving fast and having adverse geometry settings, which also tend to wear outer edges more as the tyre wall will roll under. Requiring higher pressures to counteract.

Up for watching Scotland v France by the way ?

Hi Andy
Yeh I am up for the Scotland France Game. Looks like there could be a few if us heading into town for that one.
Re the comments on tyre pressure. I always kept a close eye on the tyre pressure and still do. As you know I had my last Scoob for several years and went thru a few sets of tyres. The Goodyears were the 1st set and had tyre wall cracks when there was still a fair amount of tread left on them . The couple of sets of Pirrelis I put on it did not suffer from tyre wall cracking.
The alloy wheels were starting to get porous when it got to about 9 years old so if anything it was the Pirrelis that were most at risk of suffering from underinflation and hence cracking, but they did not. The problem with the Goodyears was a few years back mind you, but it is interesting to hear comments being made about it now.

Cheers Stev,
As I say, will probably go for the Toyo T1r's or the Michelins since they seem just about as good as the Goodyears, but without this "risk factor" of excessive wear on the shoulders or side splitting. Found them ok on 2wd cars, but 4wd may put more stress on the poor blighters !
Yeah, see you on Saturday. Bus about 3.45pm d'ya reckon ?

340 bhp ? Well that's still 67bhp more than me ! Is it laggy ?
Anyway, have ordered Toyo TR1's, 91W rated. 4 for £390, fitted locally.
Thanks for all your thoughts folks !
