15” Tires for 8” Front and 10” Rear BRM style wheels to go on an RCR40

[Randy Folsom]

Hoping for some guidance / sources for 15” tires for 8” front and 10” rear BRM style wheels to go on an RCR40. I would like a period correct look, i.e., big, bold lettering. Also wondering if there is any preference for bias ply vs radial. Not going to go with Avon or similar because this car will be mostly used on the street with an occasional track day.

Cheers, Randy

 

Why not go with Avons (while you still can)? My car is used exactly as you intend to use yours (i.e. mainly street use with the very occasional track day) and the Avons have been superb. In fact I have another set sitting in the basement ready to be put on in another 200 miles or so. Only drawback was having to paint the lettering on myself.

The Avon cr6zz tyres are exactly what you need. They are pricey but excellent. I have been using them on my GTD for 15 years I use 215/60 x 15 front on 8" wheels and 275/55 x 15 rear on 10" wheels. Mostly road use with occasional track use - perfect for both. Everybody I know uses them on 15" wheels.

My concern with Avons, and similar, is that my engine dynoed at 533hp and has ridiculous low rpm torque. My understanding is that if I accidentally side step the clutch with those sticky tires, the drive train could fail.

Are your Avons bias ply?

Thx for the info. How many miles can you get out your Avons?

 

Mine have done 11,000 mikes. There's still maybe a 1000 to 1500 miles left on them, but I figure I'll change them soon to be on the safe side.

Hey Brian, What size of wheels and tires are you running?

10,000 is plenty of miles for racing tires on a street car. I might have to reconsider.

 

My wheels are 15 x 12 and 15 x 8.5. Tyres are 295/50VR15 and 215/60VR15.

How much are the Avons? Fran says I need the following sizes for the RCR40 with BRM Rims:

205/60/15 and 295/50/15

Looks like they are still listed on their web site I will give them a call on Monday.

Well it turns out they don't list the 205/60/15 provided to me by RCR for the front BRM rims. And a 205 seems to be too narrow for an 8" rim in any case.

Mike, who did you order from? Cheers, Randy

 

[Phil G]

I just checked...mine were 215/60/15 and they fit fine.

They do list the 205/60/15 for the front, but not the 295/50/15 for the back
