FinalDrive Posted September 29, 2005 Anybody have any advice as to a good, modern "all-around" tire for my 1978 TT? What sizes do I need? I have one source that says 300X21-Front and 460X18-Rear but those numbers don't jive with the measurements I see for most retailers products available nowadays. Any help is appreciated.

originaldirt Posted September 29, 2005 I like IRC GP-110's for 50/50 tires, and Pirellis for 20s/80d tires. Modern size conversions would be 80/100x21 and 100/100x18 , however I'd run a larger rear tire like a 110/100x18 or a 120/90x18. OriginalDirt Share this post Link to post Share on other sites
FinalDrive Posted September 30, 2005 Thanks much for the info. If I elect to go with a bigger tire on the back would I be able to fit it on my OEM rim? What about clearance with the swingarm, etc.? THANKS! Share this post Link to post Share on other sites
FinalDrive Posted September 30, 2005 I probably should have clarified that what I meant by "all around" tires was all around in the dirt, mud, sand. I do NOT ride this bike on the street (except to get it to the dirt, which sometimes might be down the road a bit! ) Share this post Link to post Share on other sites
OregonTrail Posted September 30, 2005 OK, depending on how much you want to spend...that's the real question. I ran S-12 & M-12 on mine for racing, but for trail riding you could save a little money and run some IRC Volcanduro's , a 80/100-21 up front and a 120/80-18 or 110/100-18 in the back.

junkyard dog Posted October 1, 2005 I also tried the S-12 or M-12 for racing. Good tire when new but wears fast. My favorite is the Metzeler MC 5. Very durable with good handling characteristics. Have also tried the Volcanduro and hated it. Share this post Link to post Share on other sites
