Front runner speed limit

[Coothethird]

So, are the goodyear front runner tires still passing tech for, say, 230 mph?

I was wanting to run goodyear front runners (2989 front, 1966 rear) in a 220 to 230 mph class, but I can't seem to find if these are still allowed.

Our class record is 242, no change in tires to my knowledge

They look a lot like LSR tires to me...
hey they look fairly wide, maybe the same ones John and Troy run   

Yeah, looks like our 10 in tires. The 23 x15 are 5 in wide

Are the Mickey Thompson ET front tires still being approved? Or did the goodyear buyout change that?

We?ve run Goodyear Frontrunners on our front wheel drive Volkswagen over 220 mph at least 50 times. Our records are 234.xxx, 241.xxx, and 244.8 mph. We?ve never had a problem. We change them after 5 or 6 seasons when they start to crack a little.

A question for the veterans of Bonneville and Dry Lake.

Now that I have an ideal power increase for my 50cc engine (32 horsepower), I would like to ask again about tires.

Goodyear's Front Runner seems to use an extremely hard compound, but will it be okay to apply driving and braking force? Or will it wear out in spots like when you try to erase writing with a rubber that is too hard? I'm a little worried because I can't find any 32 horsepower class motorcycle tires that can challenge 250km/h. I'm aiming for 250km/h because if I can't aim for 250km/h on the salt flats in good conditions (that is, with desk calculations and experimental driving on paved roads), it's hopeless to break the Buddfab record.

Sorry, I forgot about your previous advice. I was going to use the Goodyear D2904 Land Racing as the rear tire, but I mistakenly thought it was the Front Runner. Has anyone used the D2904 on the rear of their bike?

I run the D2904, 22x4x17, on the front of my motorcycle,, a number of 200+ passes with a best to date at 228mph, no problem  8-)

Thanks,stay`tee.


Did you feel it was okay to apply braking force to the D2904 on the front?

I think other Landspeed tires are fine, but I'm a bit worried about the D2904 because it's also a front-runner.

sorry, cannot answer your question, as, for safety reasons i have no front brakes 

[Takatsukasa_Fumio]

Thanks,stay`tee.

Come to think of it, the standard is that wheel brakes on a streamliner can be installed on either the front or rear, but it seems that everyone has them installed on the rear.
Is the reason they're not installed on the front wheels really to prevent falls?

Reading other threads on the forum, it seems that there are cases where Front Runners have been used successfully on front-wheel drive four-wheel vehicles (no problems when driving force was applied), so I will look into this a bit more.

For the bike I'm researching, I think that initial tests suggest that motorcycle tires with an appropriate rate such as those made by Bridgestone would be fine.
