They are about the same as Colway, Indysport etc - a remould slick with a minimum tread pattern. Lacking in ultimate grip compared to an expensive brand but they are cheap and perfect for trackdays IMO. Much better than running a road tyre. I ran Colway F2s on my 205 last year which were good and lasted well. Speak to Ears motorsport. They sold me some Indysport tyres when the F2/RB5 didn't come in the size I wanted for my Indy. Even in the soft compound these have held up pretty well.

you asked for opinions and I gave mine. How is that not useful ? I wouldnt recomnmend them as ive been told by another track go-er they are not particularly good
they are a cracking tyre full stop. take into account the price and they are untouchable. i used all sorts including yoko's/pirellis on my trackslag e30, the grippiest were medium soft rb5's. (of course race resukts may prove otherwise but for a trackday who cares?) with a choice of (iirc) 5 compounds and about 45 quid a corner you can't knock em. (actually you can - they are a bitch to balance - need tonnes of lead but again who cares on a track car).
re pressures... i think its impossible to advise because there are so many variables like tyre compound, vehicle weight and performance, suspension etc... mine were lower hot pressures than road tyres but similar to other r compound iirc. i experimented on an open pitlane day at bruntingthorpe, and just stuck with something that seemed to work
Have you got a rough figure that you ended up with, i assume on your 325 (same car as me)? I'm running at stock pressures and they look like bloody bike tyres!
I know what you mean about the blanacing too, i've had to send one back as it was 270grammes out and they couldn't get it balanced. The rest seem OK, but do have a lot of weight on. If i could afford it i'd get Yokos, but if i could afford them i wouldn't have a shagged out old 3 series!

look at the pic in my profile - they do bulge a bit!
sorry really cant remember my pressures, was 2 years ago - might be worth giving the supplier EARS a bell, they were pretty helpful IIRC.
yoko's simply arn't worth the extra £100 a corner IMHO there are better ways of making a few tenths a lap!
(incidently the impreza above is on yoko advans - less grip imo)

ah! I honestly didnt read the bit about pressures, so my reply would have seemed like a useless reply, oops.
I read the subsequent replies also and someone mentioned yokohama's are £100 a corner more ? Well I only pay £100 a corner from george polley and wouldn't use anything else for a rack car. I've used Avonsemi-slicks on my caterham's.
I'd assume pressures would be similar to yoko's, so I use 23 PSI cold (front) and 27 PSI cold (rear) for my 780 kgs 205.
I know someone who used the RB5s then moved onto the yoko's and thats where the "they are crap in comparison" comment came from. Yes they are cheap in comparison

What size tyres do you run. I get A048R's for about 60 quid a corner - From what I've seen of the RB5's they are not that much cheaper than the Yoko's.
Those presures seem very high for the yoko's, my car is around 100kg's heavier but I start much much lower to stop them going off after 20 minutes. What are the presures like after a run - they must be sky high?

Never used them but are the sidewalls really harder than road rubber? just that a mate ran the colway inters which are a similar tyre are road tyre carcasses & the sidewall flexes quite a lot vs new R rated track tyres.
Pressures wise can't help sorry, dont think whats suitable for mine will help you, can't think you'd want to go more than a warm- pre session pressure of 30+ tho, so maybe 25 all round & see how it goes I just use manufacturers road pressures as a guide & just play about & see how get on, check before & at end of session & see how they rise & how you felt on them, its an individual thing, I ran my slicks at dif pressures to some mates, was just a happier with how they felt, winter track days I run a good 5psi lower too.
