Piran Posted December 11, 2002 Share Posted December 11, 2002 I put a couple of Goodyear F1s on the back of my Supra a few months ago, I have now done 5000Km (about 3000miles) and they are completely slick - now I don't drive particularly harshly and this has caught me completely by surprise, what sort of life are people getting from F1s ?

Gaz Walker Posted December 11, 2002 Share Posted December 11, 2002 About 6-9k miles if you drive normally I would say? Gaz. Quote Link to comment Share on other sites More sharing options...
Piran Posted December 11, 2002 Author Share Posted December 11, 2002 I had Kumho tyres on before (new on when I bought the car) and switched to Goodyear partly because they Kumho didn't last very long about 4000miles. what would cause the car to be particularly heavy on rear tyres ?

Piran Posted December 11, 2002 Author Share Posted December 11, 2002 No wheel spin and very little hard driving - basically I only do about 30-40miles each day on A roads with a fair amount of traffic so I can't throw it around much anyway !

Terminator Posted December 11, 2002 Share Posted December 11, 2002 It is too early to say, my F1's are on the front. Iwill check at the week end. I will also check my SO3 rears and see how they are doing. Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted December 11, 2002 Share Posted December 11, 2002 Theres definatly something wrong here. I had Kumho's on my car, new when I bought the car and I got 11,000 miles out of them. In fact they were only just touching the wear markers on the best part of the tread but had worna bit more on the inside edges. I then changed to Goodyear F1's and since the change, I've covered 5,000 miles and they still have plenty of tread left on them. More importantly, I do drive the car quite hard and still get a respectable milage from them. Are your tyres wearing all over or just the edges - Worth getting your geometry checked?

Piran Posted December 11, 2002 Author Share Posted December 11, 2002 the wear is even across the tyres and it's both rear tyres althought the pasenger side is slightly worse (no tread at all) than the drivers side (.5mm) I hadn't even thought about checking for tyre wear this early and so hadn't noticed them go ! it's only in the last week that I noticed the grip getting really poor - and now I know why The suspension has been lowered and stiffened so I don't know whether this could throw things out ? and it's got stock traction control which has kicked in about 5 times since I owned the car.... It really doesn't sound right - I mean we're into motorcylce territory for tyres here ! and I can't afford to replace tyres every 3months !

Ian C Posted December 11, 2002 Share Posted December 11, 2002 Do you do a lot of junctions/tight low speed turns (i.e. 1st gear 90degree) and do you have a limited slip differential? -Ian Quote Link to comment Share on other sites More sharing options...
Andrew Dunk Shaw Posted December 11, 2002 Share Posted December 11, 2002 My last set of F1's did 11,000 miles on the rears, if the wear is even across the tyre then it sort of rules out wheel alignment and tyre pressure. Cant quite believe youve only got 3000 miles out of them unless your the local burn out guru. Quote Link to comment Share on other sites More sharing options...
Piran Posted December 11, 2002 Author Share Posted December 11, 2002 I do 11 junctions each way so not a great deal. and I really don't drive hard at all - can't drive hard for most of the journey as it's through 30mph zones and the rest is often behind a tractor !

Piran Posted December 11, 2002 Author Share Posted December 11, 2002 in oxfordshire it's difficult to tell the difference between on the road and off the road ! - in fact off the road probably has a better surface (certainky flatter) Quote Link to comment Share on other sites More sharing options...
Terminator Posted December 11, 2002 Share Posted December 11, 2002 Stock TC on a Jap spec cuts in at about 13% slip. Anything below that and the system wont react. So you may be spinning more than you think. When using RLTC in monitor mode you would be surprised to see how much low level slip you get in relatively normal driving. That still does not explain why yours have gone off so fast, because most of us would get some unnoticed slip. The only tyres I have heard of going that quickly were Yoko's Quote Link to comment Share on other sites More sharing options...
Ian C Posted December 11, 2002 Share Posted December 11, 2002 11 junctions is a great deal each way every day If you have a limited slip diff, every junction will cause the inner wheel to chirp a bit as it's trying to move as fast as the outer wheel - obviously this causes wear on the tyre. Doing it over one hundred times a week is going to take some sort of a toll in the medium term, I would have thought. This isn't scientifically proven, it's just the only reasonable explanation I can think of for the rapid wear of the rear tyres. If the junctions are pretty evenly balanced left and right the wear should be similar. -Ian Quote Link to comment Share on other sites More sharing options...
Andrew Dunk Shaw Posted December 11, 2002 Share Posted December 11, 2002 Are you sure you wrote down the right mileage when they were fitted I agree with the more left n right turns the more you wear your tyres but find it hard to believe 3000 miles compared to my 11,000 miles on the same rubber, my journeys day to day involve , more than 11 junctions, 10 miles of M way and quite a few miles on country rds that have seen better days. Perhaps your F1's are really a set of race wets Quote Link to comment Share on other sites More sharing options...
Piran Posted December 11, 2002 Author Share Posted December 11, 2002 Nope definitely got Goodyear Eagle F1 Gs-D3, and I was concerned about only getting 4000 miles off the original Kumhos so I set the tripmeter etc. definitely got about 3000 out of these and am concerned that there might be something else wrong to put this much wear on - have just ordered some Kumho replacemnets as it'll give me a few extra weeks of life in the tyres !

Dont wish to sound like im taking the p, but they are fitted in the correct rotational direction aren't they ? Im just trying to think of a reason why you got such shit mileage.

Piran Posted December 11, 2002 Author Share Posted December 11, 2002 I believe they were fitted correctly and this has all happened between it's last service and it's oil change service which is now due ! so no nobody else has driven it !

lust2luv Posted December 11, 2002 Share Posted December 11, 2002 Sounds well dodgy to me, where did you get them from? Could they be knock-offs? I've had over 5,000 miles out of my rear D3s now (low, stiff car), with a fair amount of hard driving and a bit of wheelspin. I checked them for tread just the other day, since the back end kicked out accidentally for the first time since I'd bought them, but it must have just been the very cold road, cos the tyres have *loads* of tread left.

Guest Terry S Posted December 11, 2002 Share Posted December 11, 2002 It might just be a bad batch. Have they got exceptional dry weather grip. That's the kinda return you'd get from an R compound. Quote Link to comment Share on other sites More sharing options...
Gaz Walker Posted December 11, 2002 Share Posted December 11, 2002 Maybe take em back to the place you bought em from & complain. As long as you can prove it... Gaz. Quote Link to comment Share on other sites More sharing options...
