Hi Guys,

I am looking at getting federal 595rs-r for my track saph.

I am on 17" wheels currently using 215 40 goodyear eagle f1 which is a great road tyre, but the federals done do a 215 40.

can I get away with using a 215 45 on the front and a 225 45 on the back, without catching on anything?

I know the front shocks are close but not sure if anyone has used them?

any help appreciated.

thanks

Adam

 

I have just found them in 215 40 so that will be fine for the front,

so the question is would 225 45 or 235 40 be better on the rear?

 

Run 215/40/17 all round and ran perfect all day at Donington

 

Thanks for the feedback.
I did think about that but wondered if i could get bigger tyres on the back?

 

PM Ridgey as I am sure he runs different sizes on his Saff mate

 

Depends on your suspension height really but with a little arch rolling quite a few people run 235/40 on the rear.
I,ve just about got 235/40 kumho v70 to fit on the front as well with a little persuasion not tried these on track yet though.

TBH for the last few yrs my favourite for track has been 225/45 16 all round. Was running these last Sunday at National Day.

 

What rim spec do you have ? 16x ? ET ?

 

They were on 8x16 et32

 

Sorry to jump in....

Are the Kumho and Federals a cheaper alternative to Toyo R888's?

Thinking of getting a set of toyo's soon, but could be swayed if there is a similar tyre for less cash

I was really impressed with the federal at ford fair. I don't have much to compare it to track tyre wise but it was good.

 

Been hearing good things about both the federal and kumho.

Dont think the Toyo can be beaten, but if there is something close I'd be happy

 

Kumho v70 is a track tyre like the r888, but better IMO, they don't overheat the same as the 888's do. They do tend to be cheaper as well.

The federals are a road tyre, with road compound so are not a match to the above 2. The kumho and toyo become a very sticky tyre when warmed up.

 

Thanks for clearing that up mate
