New tyres and pressures?

[mak]

Hi, just got my new wheel's fitted on sat and i'm running toyo t1r tyres, i've done 150 miles scrubing them in and today i've started to eak out a little more cornering speed but i'm thinking they feel like there tucking in i'm running 25 psi front and 28 rear but before i start upping the presure has anyone else got a ball park figure for pressure there running and are happy with that suits these tyres.

Woah!!
Bring um down to 24 allround.
They'll move around on the rims at those pressures!

New tyres with taller tread and softer uncured rubber will generally work better with lower pressure. This increases the contact area and reduces the stresses on the tread blocks. It's also worth curing the tyres properly, this will harden and toughen the rubber resulting in more grip and less wear.

I'll give them another 100 mile at these pressure's then and after that i'll see wot they feal like when pushed but at the moment they fell a little soft on the side wall, allthough over all a hell of a lot better than the origanal 15 front and 16 rears.

How do you do that then?

Hi all
I replaced my rear tyres last week also with Toyo T1R's.
how do you 'cure' your tyres and what is the benefits of doing this?
Cheers

You need to get them up to around 50C (which is just too hot to hold comfortably) and then let them cool down naturally. Heating is done by repeatedly accelerating, cornering and braking close to the limit of grip but not actually sliding. You need to find somewhere quiet to do this and make sure you don't upset anyone around you. In the winter it can be almost impossible to get the tyres hot enough; this time of year it will probably take around quarter of an hour. Each time you do this the tyres will cure a little more, but the first time makes the biggest difference.

Has anyone tried Goodyear Eagle F1 GSD3 on their Chim instead of Toyo Proxes or SO3s?

Ive just replace one of my rears a dunlop sp2000 the one it replaced was only three months old but it got a puncture and was not repairable, the guy at the tyre place gave me a funny look when i told him to put 24 psi in it

24 psi does sound a little low for a rear does it not i no we run low pressure's on these cars but is that not something to do with the old bridge stones haveing a hard side wall ?
Is it possable a more modern tyre with a softer side wall and lower profile could pop off the rim with low pressure and hard cornering

Pressures do vary but on these cars 22 front / 24 rear wouldn't be unusual.
