Ok, having read this thread https://www.s2ki.com/forums/index.php?showtopic=698905

I noticed that boab01 mentioned pumping up Eagle F1 Assymetrics to 36-38psi, question is how do i know if i have assymetrics?

I have checked on my eagle F1 tyres (think its gsd3?) and see no mention of assymetric only directional therefore i presume i dont have assymetrics, i pump mine upto 32psi all round.

Cheers

 

By my understanding if they are GSD3's then they are not Assymetrics! Totally different tyre i believe.

 

It will say Asymetric on the tyre.

 

I 'think' your right mate, i have never fitted eagle F1's TBH i only ever use bridgestones just the alloy wheels i bought came with eagle F1's.

 

Pics?

 

F1 gsd3's are v tread. Asymetrics are not !

 

Goodyear F1 GS-D3 are directional but symmetrical. This means that the direction of rotation is improtant but either side wall can be on the outside. The direction of rotation is marked on both sidewalls. Once Fitted on the wheel you can't move that wheel to the other side of the car without refitting the tyre the other way round. On an S2000 because front and rear are diffent sizes you can't move it anywhere else.

Goodyear F1-Asymmetric are designed such that the tread at the inside wall of the tyre is different to the outside. The outside wall will be stamped as such. It can rotate in either directon. Asymmetric tyres can be moved from one side of the car to the other.

Some (few tyres) are are asymmetric and directional. This means that that you would need to buy two rights and two lefts, I don't know of an example of one of these.
