Tire suggestions

Postby Cafe Freak » Mon Feb 14, 2011 12:21 am

I am putting my 86 Canadian rz350 together for formula vintage ( hope thats not a bad topic). I am done with most rebuilds and upgrades and am getting close to ordering tires..Question is where to order and what brand will be best.. I like the Avons in a 110/80 18 and 120/80/18 but arent they tube type? These wheels are tubeless 2.5 front and 2.75 rear and are stock for this model. I say its an 86 but build date is 10/86 could be an 87.. What brand is there that is tubeless, 18 inch racing compound and who is a supporter of AHRMA that I can order from . I will be running Avons on the f500 RD but as you can see I am in need of help with the RZ.... Thanks...Doug Bradley

I saw your post but I'm not real good with 2 strokes. I run a mixture on my old triumph. An avon on the front and a dunlop on the rear. I bought them from RC Barker who advertises on the AHRMA web site and is in the rule book. He sells both avon and dunlop. His web site is www.rcbtires.com . One of the BMW guys is selling Heidenau tires from Germany. His web site is www.motorradavl.com . You could talk to him about something different. Hope that helps a little. Several of the guys on this board run smokers and should be able to help you on specifics. Good luck.

Thanks Ken, I have looked at both sites after seeing them in the old rule book,and have seen some of the threads on the heidenau tires but dont know much about them. My next step was to call Rick from R3 racing up in Hayward. Maybee I will call RCB tomorrow also and get some input.. Thanks again Ken... Doug Bradley

I would tell you to go for the dunlopes if in stock.Think how much a crash cost.You wil get the best life out of them to. I run them till they run out of tread, no shit.

+1 on the dunlops.

Also, make sure you don't get any tires that are more than 2 years old. They all have a 4-digit date code on them that's WWYY (Week, year). This information comes to you courtesy of the one and only Phantom309 (at least it came to me that way when I was sitting in the pits with bent forks and roadrash wondering what the f*** happened). If they're more than 3 years old, they are garbage - ask me how I know) :roll: .

I have a question along these lines: The SR500 I bought to race had been raced in WERA and came with Avon AM18's front and rear. The numbers I found stamped on the tires are W1406 and W4901. Are these the date codes? Looks like I need new rubber before I hit the track. Just wondering is a supplier will have these for sale at Cresson?

Chris, those are not date codes, or if they are, those are some funky old tires! I don't know Avons so well anymore, but those are probably compound numbers. Date codes are week and month. eg: 2310 would be 23rd week of 2010.

Very rarely is there trackside tire service for vintage tread tires. If I were you I'd call Bob Barker in the morning and have him drop-ship tires directly to the track. He supplies Avon and Dunlop race tires.

Good luck.

Thanks Kenny, I bought the bike back in 07 and it had these tires on it. I'm not in a big hurry for the tires as I won't be ready to race for Cresson, just coming to watch and learn. I want to put in a couple track days before I enter a race.

I've tried for some time to figure-out the codes stamped into Avon race tires. Nobody seems to know.

Anybody here have an idea about the codes stamped into Avon race tires?

I have found, however, the following interesting article about initial heat cycling:

"W1406 and W4901"


The date code is often preceded by one or more letters and numbers...haven't been able to figure out what they mean.

I contacted Avon about this a few years ago and here is part of my email and the relevant part of the reply.

Me:
The tyre doesn't have a DOT number, it is a race compound one with "Not For Highway Use" stamped on it.

I have found two numbers on the right sidewall of the tyre, both in seperate 'raised' blocks, one reads 4560, the other reads 3003, the last one is prefixed with an 'X' type of mark.

John Leach of Avon:
The first number you gave me is the part # for the tire (4560), the second number (3003) is the date of manufacture, 30th week of 2003.
