Appologies in advance for another tyre thread.

Need new rubber all round on my 92 griff. Currently has 225/50/15 front and 225/50/16 rear, all Eagle F1's. Been really happy with them although I've never had anything else to compare them to.

Looking at the various manufacturers website is a minefield - they all go into detail about compounds, flanges, centre zones etc but I dont really understand it all, how the hell do I compare them? Basically what I want to know is:
which ones tend have longer lasting compound?
which ones grip best in the dry? which ones grip best in the wet?
which one is the best compromise of all three?

I'm trying to compare bridgstones (SO3), goodyears and toyo's. I'm happy with the current sizes so I'm not interested in different size permutations.

Is there a decent website somewhere for comparing tyres? If not then there bloody well should be!

Try this website for loads of comparisions:

www.tirerack.com/tires/surveyresults/index.jsp

I'd be very interested to hear of F1s compared to S02/03s on a TVR, as I've run F1s in the past (on a non TVR) and was very very impressed.

Cheers

I have only run on SO 2's and IMHO you are running on the better tyre now. I found the bridgestones cr@p in the wet.

The bad thing is that Goodyear don't make the gsd 3's in both sizes.

Thats the reason behind me buying 17" rims, so i can run the same pattern all round

I find the Bridgestones excellent in the wet!

I suppose it depends what you're comparing them to. I was amazed at the F1s ability in the wet compared to the old tyres (Michelin Pilot crap things.)

I recently tried to do the comparison to work out which was best..... everyone has their own view, so in the end I went with Toyos, and I'm really pleased with them. A few locals also have them and are really pleased with them. I've got Eagle F1s on the tin top, and am really pleased with them too, however, they don't do the same pattern in both sizes for the tiv, and when I e-mailed them asking if they planned on doing them in the same size I got:

Goodyear said:
Thank you for your interest in the Goodyear brand. Unfortunately we do not produce the same pattern for the front and rear of your car as you are already aware. There are no plans at present to produce the F1 GSD3 in the front size. The only thing I can suggest is the Eagle Ventura pattern which is available in both sizes and is also a directional pattern. I hope this information is of some help.


The Ventura is a V rated tyre..... so they clearly missed my asking about Z rated tyres

factory has done "extensive testing" over the last few years.

they reckon, Toyo proxes...ALL the cars were set up for them!

but then toyo breached copyright...so now they're no good?!

now all TVR's are on goodyear F1's (there are no 15"ers so there's no prob)

these were their second choice so should be pretty good anyway!

I found...toyo' to be grippy but incredibly soft. attritian rates are quite high and grip about the same as bridgies tho they feel much stickier. breakaway a bit tighter...which i don't like (pers pref)
my toyos are wearing quicker than the bridgies, the car set up had to be changed and they appear no faster.

will try F1's next (i have 16"ers all round) as that's the way the factory went and if they are as grippy with a stiffer wall..they SHOULD be the best compromise.

but as steve shpub has said ANY times...all the sprinters/etc use bridgies, so if you want to bolt on the the best known tyre, it would still be my recomendation.

The effects of tyre pressure and condition is often overlooked when people compare tyres. Before you can compare tyres fairly you need to be sure that you've got them at the right pressure, and that may not be the same pressure that suited your old tyres. The optimum tyre pressure will be different for different types and size of tyre and will also vary depending on the condition of the tyre and even (if you start getting fussy) how grippy the road is.

This may well be a daft question..... I have the Toyos at the pressures as per the handbook..... how would I know or tell if they are the best pressures for those tyres? Is it a case of trying different pressures and seeing how you get on?

Im sure you'll find info on here regarding the correct pressures for those tyres

pressures are determined by car weight etc,

factory spec...as per brdgies (but i add 2psi all round)

When I went for my Toyo's (17 and 16"), the Dutch distributor calculated the right pressure for the Griff, using weight and power input. They came up with 2,0 bar (around 29 psi). I must say I run them slightly lower on the front.

something to do with using TVR name (possibly actually on the tyre) without coughing up.

so the official line was "we haved moved away from..."

as i say they are now fitting the goodyears, but i am fairly sure i saw a new Tamora on them at peninsula, but this could be an earlier registration.

they don't sell many of those fine cars.

That seems a shame, I know they had formed a good relationship with Toyo, still a contractural dispute doesn't mean the tyres are no longer any good does it. Rich...

Thanks for all the replies. I didnt realise the Goodyear GSD's didnt come in 15", I've got an older model of F1's on my car and just presumed they would do the GSD's in the same sizes. I think I'll go with the SO3's seeing as I can get them at cost price. It'll be interesting to see how they compare to my old F1's.

V rating is "up to 150mph" and Z rating is "up to 149 mph", so presumably V would be just as OK as Z. Or am I missing something?
