Toyo R1R vs advan AD08

[Beddie]

Does anyone know what MM of tread comes on the AD08 and R1R?

Ad08 sounds good so far then  

AD08 comes with 8mm when new as it's marketed primarily as a road tyre, i'd imagine the R1R also comes with the usual 8mm compared to the 5mm of the 888  

Thank you   was confused about the whole "R888 don't come with lots of tread"
Answered that question great  

No probs mate 

Although a quick double check shows the R1R coming with a stingy imo 6.5mm when new  
R888 is definitely 5mm and AD08 8mm though

Excuse my ignorance but is the normal load rating 92 then on most 225/40/18 tyres but some of the semi-slicks have a lower load rating of 88, which could be a potential problem if pushing too hard/invalidating insurance?

R888's are the only track tyre ive seen with a load rating of 92, ive not exactly gone out of my way to look at the others though.

any idea on the technical reasoning as to why they would have a lower load rating? compound?

Running AD08's on my Evo and have been very impressed so far . Not worried about wear rates as I hardly do any miles each year.   

Currently running PS3's on the wifes bog standard Gti which also seem pretty good .

I would buy the AD08's if it was my choice between the Toyos and Yoks.

Mainly as they have motorsport in mind and therefore the cars they go on are normally stripped out lightweight track slags.

So is it safe to run 88 load index tyres on the golf?

I looked at both the R1R and AD08 2 years ago when i needed something to go on track with, as i recall it the AD08 is a bit harder compound that the R1R. Also i've heard from some guys in Denmark runnig the yokohama cup that the AD08 is noisy and lacking grip when really giving it the beans.

At my level of performance the R1R is the perfect tyre in between the R888 and Michelin Pilot Super Sport, so it's actually the best of both worlds. The grip is awesome and it's an easy tyre to read. I've done app. 13.000km on them including trackdays and there still rubber left to make them roadlegal 


All in all you won't be let down by the Toyo R1R's

Volkswagen puts 88 LI tyrers on the ED35 if you order it with 19".

From what I remember tyre pressure recommendations are +0.2 bar higher than for 225/40 R18 92Y.
Put 2.7 bar in and you are on the safer side.
