if you're going SRS BZNS on grass-o-cross, or just doing something more serious to begin with...
OD of the tires is the last component of your gearing - spending $$$$ on a short FD all goes out the window if you throw too tall of a tire. 59-62cm OD seems to be a pretty reasonable place for 2wd cars. 59-60cm means you're running 14s, 62cm is a fairly rare set of 15s. By and large, it doesn't seem like anybody gets rid of these tires used - most of the used market seems to be open-class 65cm 15" tires. KF7RWG http://www.utahrallygroup.com |

yeah plus Juan.... gravel tires are not just stiffer than sheeeeut, they're really temperature sensitive...ie you don't get them squirmin, they don't get hot,and they don't get hot and the thread doesn't soften up and comply... So once again, horses for courses.. Out cheeer in the PNW the bulk of the rally crosses have always been nonsensically tight like maybe snick it into 2nd maybe then back to first. Then it sometimes rains, and sometimes is even cold...Snows worked better than real rally tires... The gearing deal IS important but realistically only in stage rally since low gear is low anyway and you are in low--like 1st 2nd in many (too many) grass-o-crosses.. On STAGES you'll be in the 3rd - 4th and that's when lack of power, and lack of gearing hurts by making acceleration SLOW just when you want it to be quick.

John, would you recomend this size for the Fucus also? Hows that appendix, hope you are well![/quote] Yeah. My ol' favorite Michelin for my car was called "14-62 x 15". It was developed according to Michelin for 2 liter cars around 200 bhp... 14cm across the tread 62cm tall 15" wheel Plenty of grip, not insanely heavy, in fact fairly light... All the Subu-bitchi and Mister-buru guys use typically HUGE things same like the WRC guys use... But they're nowhere near the same power or aggressiveness, so their used tires are too big.. It would be real nice if they used more sensibly sized tires so we could buy their used tires, but like spring rates and turbo sizes, in America, bigger is always better... Snot.

Although the top spec open cars in Rally America (L'estage, SRTUSA, SRTC) are actually more powerful with more grunt than a current spec WRC car. (More CC, Larger Restrictior, higher engergy fuel) But in general, you're right. (And, of course, most cars aren't driven to their potential.)

Don't confuse his mk4 2000 Golf at ~3000lbs for an mk2 or mk3 golf at 500-600lbs less. The mk4 was built for larger wheels & tires than the mk2 or mk3 could ever fit inside the wheel well. And has stock brakes that are too large for 14" wheels. If the mk4 is making over 200hp, I would say you could run the moderately bigger tires. Otherwise, John's suggestion of the 14-62 15" from Michelin is the way to go. ____________________________________________________________- One.

The engines MAY have potential---if somebody like the dyno operator opens the throttle. Haven't we seen that many "Open" cars are sub 180 bhp max, and just listening we can hear the cars are not DRIVEN max... And larger restrictor? How's Canadian 34mm bigger than FIA 34mm? And a 34mm restrictor on a larger motor is going to hurt more. Whatever...more trolling..

John--
Take a Limbaugh Skittle. Antoine, Richard, and some others ARE getting the throttle open a lot more than a few years ago. Morison just said you were (in general) right and you still had to argue. Relax! I DID like the dyno operator operating the throttle line... MOOOOCH: Smile! Especially if you just took some Skittles. Andrew Steere Lyndeborough, NH KB1PJY |

I'm not talking about many cars, I purposely mentioned the top cars specifically. They are running strong tunes and are being driven hard on the stages. Are they being driven to their poential? Hard to say, but probably not.
It isn't - but since WRC spec is now 33mm... Um. Yah. Kinda. But don't you think a well tuned 2.5L engine with a 34mm restrictor will provide more torque than a well tuned 1.6L engine on a 33? Not even remotely. Just pointing out that the top cars in the US and Canada are almost certainly putting out more power than WRC cars and, therefor, can make use of the large tires that are useless as lightly used tires for most of the 'local' cars.

For 1.6 liters, on tricky turbos nobody can but, just lease..
Not even remotely. Just pointing out that the top cars in the US and Canada are almost certainly putting out more power ON THE DYNO than WRC cars and, therefor, COULD POTENTIALLY make use of the large tires that are useless as lightly used tires for most of the 'local' cars. except is the few guys at the very tippy top were driving that good, utilising all that MOAR Powerz, they wouldn't be in USA or Canada, they would be packing up in Cordoba Argentina getting ready to get back across the Atlantic to be ready for Acropolis [/quote] FTFY You want to have a thread about how almost certainly the top cars are whatever, start one...
