Speed rating? We doneed no steenkeng speeedrating. lol
I was 17, and invincible.
It mighta bin 88mph! IDK
Polyglass RWLs. Hard as rock when cold. Almost no change when hot. Squeal 'em for a city block;through two gears for sure, probably to 70 mph, or more. Nice looking tire, but junk for traction. 4-wheel slides around corners. wipe-outs when turning,leaving stopites; as in accidental 180s. slippery lane-changes. Yeah those tires were a handful.Fun after the learning, but not something I'd ever buy again. Junk compared to todays tires. 100% Predictable tho;guaranteed to be scary!
