Never had a bike with 12" tires. Im interested in getting the longest lasting tire possible so I can ride x country.

Any ideas?

TIA!

A quick trip over to Modern Vespa forum should get you some good answers. Modern Vespa GTSs have 12 inchers and many people riding many miles on them. I know, it's a scooter site, but good info. Ha, my scooter has 16 inch tires.

It's more accurate to think of tire size in terms of revs per mile...actual rolling circumference. That levels the playing field, regardless of sidewall height, which varies. From what I gather, so far, OE tire size will be very close to the 120/90 x 10s run on many scooters, ~61" circumference.

I agree with Baudler, the K61 is arguably the best road tire available in these small sizes. Depending on how & where you ride, of course, I'd expect 3000-5000 miles from the rear and 2-3x that from the front. That's based on firsthand experience, your mileage may vary:happy7:

As for "nitrogen air"...ummmm...that stuff you're breathing is ~80% nitrogen. IMO, first we got bottled water, now bottled air:greedy_dollars:

My 2012 Vespa 300 came with Michelin City Grip tires. They look new with 2,000 miles. I will get at least 8,000 mi. out of the rear, maybe more. (I got 7500 mi. on my Gixxer 1000 tires and of course I ride that much harder than the Vespa. Depends on if you do burnouts and brake hard and do wheelies. Most tires don't really wear out except in the middle from squaring off. The sides are still practically new. Not so with more advanced riders who use the sides of their tires of course when leaning into turns (see chicken strips). You might even get 10,000 mi. from the tires.

I think he is more concerned about having to change tires out on the road and in the boonies. He is planning a long trip on his Grom. 2000 can mean a new set of tires every week when you are on the road 10-12 hours a day. At least a new rear.

cheap or not HAVING to swap out sticky rubber ALL THE time inda sucks. but it's all relative. how much stickier for how much less treadwear is what's really important

2000 miles and mine look new. He will not need to change before he gets 8000 miles most likely. Should take a tire patch kit along and a hand pump. The stock tires will be a hard compound and will last a long time. 2000 mile tires would be more of a sticky tire made for the track.

Ok, then buy michelins citys then and check pressure everytime u put gas in. But you cant exactly say what ur gunna get cuz some people drive everyday upright, sum harder on sidewalls, sum only weekends. So its hard to tell what the number is going to be. But if u want a milage tire it looks like michelin is the way to go for now. Who knows maybe the popularity of this bike might get dunlop attention. But its just like how sum ask about milage it shouldnt matter you should have fun doing it. Most shops charge like 20 bucks if u bring just wheels in to em. Imma just swap the michelins sc and have fun with em here till about oct then put citys for the remander of our "winter" months in cali. But people honda made this to have fun. Did any of you think milage tire wear price of insurance when yall bought ur other bikes no u bought it cuz it was your taste. So grommers unit and smash to the big cc haters

Well for me the little 10" tires on the XR50 were really easy compared to bigger tires.

It'll depend on the tire.. Some have soft sidewalls, other stiff

I always just go to a mom and pop tire store or have a buddy do them, 10-20$ and you're done

Does anyone know if they stock setups are balanced? If not we may want to look into dynabeads for these

Small tires equals maneuverability especially with the Grom's very short wheelbase. The Honda Grom will be a bike you can turn on a dime. Light weight and maneuverability will clearly be the Grom's best points. It should accelerate very good too in town. The problem will be once you get above 45 mph, you won't have passing power or roll-on speed. Suspension also looks suspect to me. The only thing that would make it a better city bike would be if it were a scooter with no shifting and built-in storage. Hey wait, Vespa makes those. LOL

What does this post have to do with tire mileage? What am I missing?

We have a few ladies on the forum too. From what I can tell, all of them are super cool too.

Oops like dj hunny huh. Sorry but i dont see her smashing a vespa though. Figure of speech. My old work we had vespa and it was old ladys or mothers that got em for milk and small stuff. I see us getting groms with milk but doing wheelies and stoppies at red lights. Well count me in for that.

The older you get, or the farther away from a shop the more you care. but yeah lightweight bike hopefully the tires will last while, even sticky ones. time will tell.
