GreenZR, your wheels are beatuiful man!
*deep breath!*
With my 17" project going along now, I'm down to racking my brain on which tyres to select. At first I was goin' to Dunlop GT501's (had them on my first C1) Pretty impressed with them on road & mileage wise at least but I've always been a Dunlop guy.
I been hearing a lot of good about this Metzler Lasertec some manufacturers are sticking on. Well the front that is, the rear seems to have mixed reviews with having those three lines down the middle, all squiggly like. Me thinks that'd be no bueno in rain grooves & it just looks really funky.
I really do like the front though, good reviews & it looks the business for a vintage motorcycle so I'm leaning that way for the front. I saw 'em in person while drooling on that new Moto Guzzi V7 classic. (good God man... That is the most beautiful modern motorcycle made!) Anyways, I looked real hard at that front Metzler. Not only are all the reviews I read good on road grip & mileage wise, the small blocky design I think would handle off road well. They make it in a bunch of sizes perfect for my 17x2.5 too so I'm pretty much sold on trying it. For out back though I'm undecided, I'd like something that could handle dirt / gravel better with the same back road grip / interstate mileage as the GT501s. I know, I know... I want it all, lol!
But maybe I can get that... Or close at least. I found this.

I've heard all the wives tales about not mixing tires. I rarely have a matching set of tires & have never had any problems, even with cheap ass Cheng Shins. If my memory serves me correctly (which is a rarity) this tire is stock on the Suzuki V-Strom. The purpose of that motorcycle is to do a bit of everything. Commute, light touring, back roads & light off road... Hmm... Maybe I'm onto something here.
They got it there in 130 to 150 sections & they look BEEFY! All good for my 17X3.5" according to Dunlop's site (the 150 prefers a 4" wheel but says a 3.5" will work). So I think I might be onto a better combo than the more road oriented Dunlops, a hard decision for me 'cause when I do spend a ton of money on tires, it's always been on Dunlops.
I've had the GT501s on my C1, loved 'em on road & good mileage. Got Qualifiers on Bobby after I blew a JUNK Bridgestone on purpose that she came with stock. Insane grip, made the 'stones look like a freak'n joke, short mileage but my hooliganism along with burnouts & drifting attempts had a lot to do with that. I got 616s when I lived in the country & had five miles of dirt each day to work. Great all around, even dirt for a sport bike & decent mileage!
My poor six fiddy has to do it all, I take my hat off to the 'ole girl! I'm not looking for MX traction off road & will sacrifice mileage if needed. When I say 'off road' I mean like semi decent dirt & gravel roads at mostly a moderate pace. Poor, sideways dirt track imitations will be executed but then a lack of traction is in store so who cares right!
So, who thinks what? All older / wiser information will be decently considered as long as it's not along the lines of, 'you will wreck & explode & die with those tires you stupid kid!'

Tired of reading yet?
