Anyone tried 255 rear tyres ??

Can u get 16" Bridgestone SO3's in this size ?!!!
Where can I get stardard 16" SO2's from in/around the London area ???
245 is already considered a bit too wide for 7.5" wide wheels. Why would you want to increase the tyre width? Do you have a specific handling problem you want to correct or are you a subscriber to "bigger is better" (it isn't always)?

HIya guys, sorry, I know im a wedge owner in the wrong forum, but I used to have 265x45x16 (I think) on the rear of my 400SE. My rear wheels were off a racing tuscan, 16"x9". these are the biggest tyre I can fit on them, although they will take a 245x45x16 with ease.
Now sure of the wheel width on griffs, but as previously said, you might want to considder s wider rim before pushing the tyre size up that much.
PS mine does tramline like hell, and grip like warm poo on a tea cloth

Undoutably these will have more grip but if, or should I say when, the back end breaks away will it be a little more sudden and as a result harder to catch?
Probably not as the contact patch will be distorted because the 255 is definitley too wide for a 7.5J wheel, especially consideing the small aspect ratio. I reckon it will end up with less rubber in contact with the road.
There is also the small problem of clearance. I would check very very carefully that the tyre is not rubbing on the bodywork. There is not much room.

I have 255 width tyres on 8" rims on the back of my Griff and they are really too wide (at the time Bridgestone didn't make a 245x18), in fact Micheldever tyres had a job to get them on (and they sold me both the rims and tyres) I would have thought a 255 is too wide for a 7.5" rim? Rich...
About to put Pirelli PZero 255/40/17 on 17" 7.5 rims on the back of my Griff500 ( see Pirelli thread ).Will post results!
p.s. next time I'll go for the Toyo who do make a 245x18
I've just done my first trackday on Toyos. Couldn't fault them. Felt like more grip than SO2s and they give a soft/quiet ride. They might be a little softer than Bridgestones (SO3s esp. - we have them on my A6 and 'er TT so know them well), but they gripped more than my confidence did.
(OK, so I wasn't trying hard enough, but I wasn't about to knacker £400 worth of newish tyres - Cadwell was enough fund without the extra bill).

I've just put bridgestone s03 on the back of my Griff, and it does seem a more happy to break away under hard acceleration. It is so hard to tell whether this is all in the mind though! Anyone else got any similiar experiences ?

Have you lowered the pressures and scrubbed the tyres in? It is also incredibly slippery these days. Winter has arrived.

You should be setting the pressure for the tread across the width of the tyre; if you then have to lower the pressure for the tyre walls (as many say that you do) then the pressure across the width won't be right. Read between the lines - the S03PP is not a worthy sucessor to the S02PP.

What would you say the pressure should be for SO3's
Mine currenly are 24 rear, 22 front.

About right. But experiment a bit if you feel like it. Drop it a lb or two and see how it feels. A lot will depend on what you are doing and how you drive the car. And which model and which suspension you have and all these other factors. There is no hard and fast rule to this. Ideally the pressure should be set to provide an equal temperature across the tyre width but this is difficult to achieve in practice as stopping and getting out of the car to measure tyre temps and pressures is a little bit unpractical and then on much public road driving, especially in the winter, the tyres hardly heat up anyway. In all honesty, the main feedback is how the car feels and the understeer/oversteer balance coupled with making sure that the tyre is wearing evenly. Even this can be misleading as hard driving can kill the inside edges as the car starts to roll or if it has been set up with increased negative camber.
