Semi Slick Potenza 540's?

[rob77]

I've been using the dunlop SP9000's pretty happy with them in the dry and wet... nothing as serious as the 540's though.

Cause when I signed up I didnt realise I would be here for so long....I chose a stupid name...the first thing that popped into my head...dont want all my initials on display thats all.

Why do you ask? Is this unusual?

Cheers,

nah, just wondering if you can change names, thats all - without resetting all your settings and subscribed threads etc etc

[meggala]

ronin you can if you ask nicley

Thanks Buster. Ill try him again next set of tyres, but last time i got a price off him for the 540s they were like $10 cheaper each then the Dunlops. So was quoted something like $420 each for 235/45/17 (may have been 235/40/17)

Decided to stick wih Dunlops as i have nothing but praise for the guys who sell them in Sydney.

[whatsisname]

I paid $310 (255/40/17) & $280 (235/45/17) for my RE540S's.

Does anybody know who sells 540's for cheap in Sydney ? because Gordon Levin Tyres is in blue mtns right ? and its a bit of a hike.

[SLY33]

has anyone used 540's in 16inch? say 225/50 on a std rim? Im wondering if they will perform better than a 17 or 18inch street tyre in terms of ->do you get sidewall flex/rolling on hard cornering as you would with a 16inch street tyre?

Im tempted in fitting them to std rims for track, as the 16in tyres seem heaps cheaper.

cheers

I've not used either 540s or 16" track tyres, but I do use dunlop d01js in 17s....and one of the major improvements in R tyres is less sidewall flex due to much stiffer sidewalls.....so, 16s should still be great. The only real improvement from low profile tyres eg 17s, 18s, is due to stiffer sidewalls.

[Ronin 09]

Sly, i was (and will do when i need new tyres) going to do this on the stockers, but apparently the stocky rim is only 6" wide. It is more ideally suited to a 205/55 16 and they're available in 540s. They should hold on as well as a 17" when warm.

I'm guessing that of you run reasonable pressure you won't get much roll.

[SLY33]

205's eh? sounds a bit small but if they are cheap it would be ok! do you know what these can be had for ronin?

are std rims only 6 inch wide? i thought maybe 6 1/2... ive got 225/50 street tyres on stockies that look fine, do bridgestone make 225/50 16 540's?

cheers!

[Ronin 09]

I'm pretty sure they make a 225/50 16. I'm not sure where you can get them in Sydney or Adelaide, maybe do the ring around at bridgestone tyre centres?

[R32 Zilla]

Yes they do make 225/50/16 as it is this size that my boss uses on his vn comodore race car.

I know you guys are talking about circuit racing but how would these tyres go for drag racing?

With 200rwkw in an r32 using 245/40/18s with about 50 % tread iam having big traction problems and cannot get my times down to where they should be.

My plan is for when i go to the creek in about a month to fit 2 540s (used ones from the race car) to my stock rims to go on the back using about 20 psi in them.

Will this improve my launches ect.... ???

[SLY33]

apparently they do improve launches. whatsisname has over 250rwkw and street tyres were useless 1st/2nd gear, then he put 540's on and he says when warm, he can get pretty much ALL his power to the ground.
