Dynamite924s Posted April 12, 2009 Share Posted April 12, 2009 I am thinking of picking up a set of Toyo RA1's since they are now available again for a limited time - Size 225/50-15's. As far as a DE should I leave them unshaved? I have been running on Sumitumo HTR z's 205/50 - 15 ( widest 15" available in flavor) and am very happy with them considering the price, ($50 each). I am also considering other street tires in 225/50 - 15, but a set RA1's on my "momentum car" - Porsche 924S - arghh RA1's. Quote Link to comment Share on other sites More sharing options...
STRINGER Posted April 12, 2009 Share Posted April 12, 2009 I would have to say shaved...unless you only plan on running them in the rain. Quote Link to comment Share on other sites More sharing options...
laze1 Posted April 12, 2009 Share Posted April 12, 2009 Disclaimer: I am NOT A TIRE EXPERT, just an average driver I have purchased 2 sets of RA1s, both with full tread..they ran fine and had great wear in both HPDE & TT events... I am sure they are faster when shaved over full tread when new..but if you are not racing, it doesn't likely matter. Quote Link to comment Share on other sites More sharing options...
kbrew8991 Posted April 12, 2009 Share Posted April 12, 2009 *if* you can push the tire pretty decent from day 1 you'll get better life shaven to about 4/32nds vs full tread. If you're still learning, get full tread Quote Link to comment Share on other sites More sharing options...

If you're still learning, get full tread I am always still learning; although I was a little slow to discover that truth. Just looking for the longest and most consistent life for the tires; consider the first few/several heat cycles will be comparatively mild as I find new limits that I am comfortable exploring.

owenxguo Posted April 19, 2009 Share Posted April 19, 2009 If you are running in HPDE, I would say not to shave it since you are not use them for race, will last lot longer. Quote Link to comment Share on other sites More sharing options...
ddg Posted April 19, 2009 Share Posted April 19, 2009 I didn't like my RA-1's at full depth, since the compound is very soft the tread blocks had a HUGE amount of "squirm", it made quick transitions and turn in feel mushy, like I was getting a flat tire! I ended up driving them on the street for a couple of months (lots of fun!) to try and wear them down. If it's going to be a track only tire, I'd shave them.
