shaving tires (Page 1 of 2)

Hopefully not for a Lemons race...

Why not shave tires for a Lemons race?  Many tires will chunk if you race them at full tread depth.

Agreed. I would say anything maybe above 340 would require a shaving. We have ran the BFG's G-Force Sport (http://www.discounttire.com/dtcs/tires/ … p;pc=38433) with a 340 treadwear and have had no problems and can get about 2 races out of one set with no chuncking. But if you do shave or not will also come down to what type of car you are running.

For the first time this past race we decided to run a 205-40 R17 Michelin Preceda with 240 treadwear. With these tires we found out that we can only get about one race on them if you rotate them at the end of the second day. We did run these at full thread and found no chuncking with them but they did have a bit of a loose feel to them due to the tire but as it wore down this feeling started to go away.

Another good valid point. Also if you do decide to shave the tires I would suggest someone who deals with Legends cars as almost 100% of the racers shave the tires for their cars. They might also be able to build camber into those tires if you have them shaved.

Shaving is expensive.  We went through the expense at Thunderhill and all it did was make our wallets lighter and reduce the tire life from 2+ races to 1.

Rob said it best  "It's all about how much heat you put into the tires and how you manage that heat from the drivers seat"  This is an enduro, not a sprint

Ok, raise your hand if you "get" Lemons. As predicted by a friend, every race brings this one step closer to being just another all-out racing club......

Why shave new tires when you can buy used ones that are already pre-shaved?  Not to mention way cheaper.  As long as they're not old or cut, fuggit.

I agree. The beauty of Lemons is that we are not like the "others." Now don't get me wrong, the thought of going home with a car full of nickels is enticing and I hope that my team has an eye on the checkered flag but also a beer in hand and thought in mind about the amazing menagerie of parts that some teams call a race car. I say if they want to shave then let them do it. It is in the confines of the rules and in all reality I don't see a benefit. The treadwear limitation is there for a reason and if others want to squeeze every little bit out of their cars/equipment then by all means. I believe that the rules of the race will keep the spirit of Lemons alive so keep on keepin on.

I could see shaving them if you have chunking problems,  We had real bad chunking on Star Specs, but none with the Azenis.  For Lemons, if chunking is a problem, I'd look to a different tire or a suspension problem.  But you guys are right, the only shving that really needs to be done in Lemons is down low for the time lapse shots.

our star specs were excellent...wear was quite good too.....in theory shaved tires would be legal....but I don't think its worth it.....if my 3150lb 928 doesn't chunk tires.....I gotta wonder what does.....(yes we do have 2.5' of camber all around)...

we also will get at least 2 races plus a bunch of practice time on a set of Star Specs

Yes Tire Rack shaved ours for $25 per tire.

That, I don't know, I do know the shaving process heats up the tire, but I don't know if it would be a "heat cycle".

By all accounts from people in the know, shaving does reduce heat in the tire and does offer better handling, but since Lemons cars are not sprint racing nor are they full-out race cars, I just don't think there is any advantage (ie. better performance or longevity or safer or longer reliability). 

I just think with heavier cars that are prone to "tire chunking", drivers need to manage the tires a bit better.
