Tire sizing question

i was curious what tire type and sizes people are running on their 1000 vstroms. i have factory size dual sport style tires on mine currently, but im thinking about switching to a street tire because i basically use the bike to commute and just ride around. i dont really leave the pavement.

also my speedo reads about 17% high, and i was thinking of upsizing the tire a bit. dont want to effect handling in a negative way. my last bike was a suzuki GS500 and i had a SV650 rear strut/spring and a larger tire on the back. i liked the ride, just kinda curious if there was a reason not to upsize the tire in my case. also is there a way to recalibrate the speedo to read closer to correct if im not upsizing?

Larger tires can make cornering feel vague. Do a search in the Google search box above for Speedohealer or SpeedoDRD. They are devices for correcting the speedometer. For your speedo to be that far off, you must have non stock sprockets.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

You could do that. I wouldn't. I also think you are overestimating the effect a tire size change will have.

slightly higher longevity, slightly higher mpg, slightly higher cruising speed. are those things not true?

Not so much. The larger tire is offset by the lower rpm occurring at a lower horsepower section of the power band requiring a larger throttle opening. Wee riders have gone to a tooth or two larger front sprocket without any increase in fuel economy. If your Vee has a 17mph optimistic speedo, your gearing is much lower than the stock 17/41 sprockets. A larger diameter tire won't make nearly as much difference as the change in sprockets has moved the other way. Stock gearing results in about 8mph high indicated.

Stick with the stock tire size. Solve the speedometer problem at its cause.

There are several excellent street-only tires available. Michelin Pilot Road 4 are probably best in the rain. Bridgestone Battleax T30 EVO are probably the cheapest top tire. Avon Storm 3D X-M has a 15,000 mile tread life guarantee..within two years.

thanks for all your guys help. after talking to a moto mechanic friend of mine and doing some reading, and considering darkside, i have decided that i want to get either
michelin pilot road 4
michelin pilot road 3
michelin pilot activ

has anyone tried all 3 or 2 of them on the same bike?
what i would like to know is grip comparison, wear life, and wet traction.

i have a 2002 dl1000 and am mostly a commuter on it. i dont tend to use the whole tire as i live in a fairly open area with mostly straightish roads. i commute 12-13 miles to and from work. the thing that i dint like about the PR4 that i keep reading is about break-in and harder compound. as i am somewhat inexperienced, i would like a tire that would be long life and consistent as possible. havent read any real consistent negatives about the PR3 and i have had some recommendations to the Activ but it doesn't seem to be a dual compound tire like the other 2, and although it mentions a longer life.

i am kinda leaning towards the PR3 at this moment, but having trouble finding any actual comparisons, or any real life expectancies from anyone that rides like i do on a Strom...
