Default tire advice on Speedmasters

So here's my problem... and it may be a silly one, but..

I really like the look of those Avon Speedmasters, and from what I gather from the forums they're decent tires and have a lot of stick.

I went to a shop the other day to price them and the two shop guys (one of which showed me he had avons on an older bike of his) tried talking me out of getting them.. Pretty much telling me NO, and saying that I should go with Michelen Commandor II's, because the Speedmasters should really only go on older bikes that can't get up to 120 mph.

It's a good point, but then why do I see so many pictures of newer Sportsters with them? Is anyone having problems with high speeds or load weight or anything?

I really want them mainly due to their aesthetic, but that alone isn't good enough. So now Idk what to do... I want something old school looking, but I want it to perform decent. It doesn't have to be top of the line, I don't ride like a maniac.. TOO often.

Any thoughts would be appreciated.

because they're rated for up to 80mph, whereas the ones he was trying to sell me were rated for a higher speed. that's what I got from what he was telling me. Maybe "Older" isn't a good choice of word, but "slower" rather. If you disagree, I'd like to hear your thoughts.

turbomustand84, You're right. I guess the guy pulled the number out of his ass, or was exaggerating.

I just don't understand why they would be so reluctant to put those specific tires on.

Probably some liability issue with the top speed of the bike exceeding the speed rating of the tire. I had a tire shop refuse to sell me H-rated (130 mph) tires for my Mustang because it would do 150 mph. I told him I had no intention of going over 130, but no sale. I did find another store that would, though. I wanted the H-rated ones because they were significantly cheaper.

That said, I just put a Continental K112 MT90 tire on the rear of my Sportster. They look "old school" and are a tall tire, but are tubeless/tube and are H-rated for sustained 130 mph running. Yeah, like the old Ironhead could do that...

If it ain't broke, don't fix it (especially if you don't know what you're doing). Most Sportster problems are owner-induced.

I will never understand trading the performance, stickiness, build quality and durability of modern tires for the looks of the past. I was reading on another forum about a cat that wanted to run a used 50 year-old tire on his chop. At least yer not that crazy!

I like being able to throw my bike into a tight, decreasing radius turn and know that my tires are gonna grip and let me get maximum lean angle while powering out of the curve. Old-fashioned sidewall technology doesn't permit that kinda behavior. Even if it never got used, I would feel better knowing it's there if I need it in an emergency.

Yer bike is like ten years old and yer worried about "old school"? My bikes are like...old...and they get the best performance tires my budget permits. I love Metzlers, like Bridgestones and Pirellis, had good results with hi-po Avons and have never found a Dunlop tire that I like.

Good luck with whatever you choose for yer baby's shoes.

83XLX,
yeah I guess that's where I'm gonna leave it at. A "liability" thing. I'm gonna look into the Continentals. That's a real nice ride you got there, btw. I like that seat too.

You do know that in most of the pics of bikes running 40 y/o tires, they put the tires on for the photo shoot or to ride from the trailer into the show. Sure there are a few that run 'em on the road - but i don't know any.

Have you looked into Coker repro tires. Still old tech, but at least they're made with new materials...

BTW, I'm not being argumentative, I'm just trying to give some real world info. I want you to be posting on this forum for a long time to come.

Thanks for the compliments. The seat is a stock Sportster seat from 1982 that I picked up on eBay. I've had one of these Continentals once before, and they ride and handle great (and I like riding the twisties as much as anyone). Tubeless, H rated, modern rubber compound, and with a nice rounded profile for easy transitions from upright to leaning. Unless you're trying to corner like a racer, this tire is fine. The Avon is a more square tire, though, and I'd imagine it doesn't handle as well.

Hey Mosey, we're not talking about antique tires here - the Avon Speedmaster and my new Continental are current production tires, made with modern technology. Their design shapes are older, but they are new tires, not old dry-rotted ones...
