Advan A048 Semi Slicks

[Snowman]

The A048's are the worst for heat cycles. If they are going to be used for regular track work as well they only have a good 10 or so heat cycles before they really harden up. This fact makes them probably a longer lasting street tyre however. I've used one set and won't use them again.

The Dunlops seem to be the best but are $$$ which is why I use the RE55's which are pretty awesome at everything. The Toyo's have amazing grip from cold compared to the others but not as much grip when hot.

One other point people may like to note is that the RE55's (Bridgies) make an absolute bucket load of noise on the road. The Toyo's (RA1's & perhaps the 888's) are, by contrast, civilised.

Yeah the road noise really gets to me at 6am drives to Winton .

I wouldn't use it on a daily driver, especially before the tyres warm up, the grip is worse than my street tyres.

Edit: Im using RE55s.

Do the TOYO R888 heat cycle?

I was informed that they dont...

[Beer Baron]

every tyre 'heat cycles' I think what you actually want to know is does a tyres performance drop off after a number of heat cycles and the answer is yes, all semi-slicks are affected by the number heat cylcles they are put through. some worse than others, but they all are in some way.

[lukits01]

Fair enough, guess my next question is among the DZ03/RE55S/A048/R888

which one is affected more by heat cycles?

[Snowman]

A048's are the worst for performance drop offs after heat cycles. They really do go rock hard.

The Toyo R888's are excelent for road noise compared to the others. I'd use these if the car was seeing more street time than anything or if the motorosport I was doing was primarily auto-tests / hill climbs.

But for a track day tyre I'd use the DZ03's if I could afford them. But I can't so I use the RE55's as they are the next best.

Do you remember which compound of A048 you used, Snowman?

was it Medium (M) or Medium-Hard (MH)?

[Duncan]

like Gary said above, they are both the exactly the same despite the markings according to the importer

[T04GTR]

yeah. i used to use the ute ones. we have a large stack of them all with abot 1.5-2mm left on them. generally this amount lasts about 2 weeks of normal driving up and down the m2 before they are completly smoth.

pretty scary but. not bad in the rain. but at 300+ a tyre its just not worth it. thats what the spare rims with propper track rubber is for

[Duncan]

What are the utes running on these days dave?

[T04GTR]

235-45-17 meduim/hard garbage lol (pushing 1800kg with driver)

[Duncan]

lol indeed...but thats OK when there is acontrol tyre ie all on the same crap. But are they using the yoko 48r now as well? Aren't they on some dunlops

[Jackman GTS4]

How much approx are the Toyo 888 aswell as the Bridgestones RE55 for 235/45/17 ?

Anyone have a rough idea?

[Duncan]

we paid 1700 for 5 re55s in 234/45/17s from Donnellans in Melbourne for Targa

[Sick_R31]

RE55s 235/45/17 $329 each

nar they use o48r. we get (with a hard driver) 3 races and a practice out of a set. ie 1 meeting. the utes are just to heavy and peeps love flatspotting them.

[T04GTR]

top of my head the 235-34-17 ute ones are about 380~ ish

[T04GTR]

048 is good for about 10 mins. then gos off and is the same right down to the canvas.

at a test day we smashed the lap record on almost bald tyres. 1.50.05.

[Duncan]

gordon should have been happy then, thats 3 categories in nsw using them as control tyres. Shame they suck - utes used to run on basically a road tyre compound so its not wonder they are going better now - but the dunlop dz03 and bridgestone re55 are still at least a second quicker.

Haven't tried the toyos myself but they are getting a good wrap atm.
