Toyo Proxes

[gruff500]

We may have run a link on this subject before but any advice gratefully received!

Just had my rear Bridgestone SO2s replaced on my 98' Griff with a pair of 245/45 Toyo proxes. Front tyres are Bridgestone SO3s.

Definitely not settled when travelling plus 80mph as it starts to wander a little. Garage has confimed there is nothing mechanically wrong (bushes etc.) and that its 'probably' mixing the two different tyre types! Pressures are spot on from the bible - can anyone offer any advice/ similar experiences?

I've just had a pair of SO3's on my cerbie. First problem was that the wheel shop put 40 psi in them which made the drive home interesting!

I posted a thread (if you search the cerbie forum you'll find it - or click my profile and you'll see it under topics).

General consensus was that SO3's need a little lower (maybe 2psi lower) than recommended pressure in the handbook due to the thickness of the tyre wall and also most folks find they take a little more bedding in than you'd expect up to 800 miles one person found.

For the record I took the pressures down to 22psi rear (recommended 24psi) and have found that they are considerably better for it and the 200 miles I've put on them so far...

I run toyo proxies on mine and think there excellant,

Toyo Proxes all round on the Chim, and more than happy with them.......

sort pressures first.

run bridgies softer (-2) 20 front

+

toyos harder (+2) 26 rear

as discussed on previous entry for said reasons.

Interesting. So the consensus is that for stiffer sidewalls you need to reduce quoted pressure, and vice versa. I wonder why the mfrs don't allow for this when quoting their pressures?

[Guillotine]

they do, thats why bridgies on a Beemer 3series are at 32/34psi (2.5 tonnes) where as on a Griff they are on 22/24 (1 tonne).

also depends on rims, f or rwd etc.

you'll also find good racers will vary pressures for some circuits/surfaces. wear rates and surfaces can affect temps which affect pressures which affect temps etc etc.

Can you get Goodyear F1 to fit standard griff 500 wheels as these tyres were excellent on my old car.

I had them in my second Griff - they were very good...

Yes

I would think Goodyear F1's come in all the TVR wheel combos.
Have also found them good on my V8S. Think they were slightly cheaper than B'stones (£75 a corner fitted and balanced) AND tyre shop had reprints of back to back tests by EVO where the Goodyears came out on top.

I'm trying to get a full set for my Griff but Goodyear are out of stock and I can't get a date when they'll be available.

Many Thanks for the responses - will change the pressures and see if that makes a difference!
