drz400sm with q3+ tires

[dnice]

Dunlop Q3 Plus Front Tire (120/70-17)
Dunlop Q3 Plus Rear Tire (150/60-17)

im runnig these tires on my drz400sm but can't figure out which tire pressures to use, suzuki says 25/29 but dunlops site recommends a higher pressure in the front 32/30!

Max pressure?

I would go with what Suzuki says.

When I had supermoto’s I always ran them in the mid 20’s. Tough to build heat in super sport tires on under 300lb 40hp bikes. Figured the lower pressure would help.

Talk to Dunlop and let them know you're running them on a DRZ and see what they recommend. My SXV owners manual specs a similar 26/29 F/R cold pressure, which I assumed was common on these lighter supermotos, otherwise they'd be unable able to heat up properly. Or maybe those pressures from Dunlop are hot pressures?

I see @blackcamaro just beat me to the same point.

Not exactly. The choices were follow suzuki or follow dunlop. He said follow suzuki, you said call dunlop. It's still a tie. You both seem to agree that lower is likely correct though.

Edit:
I see 25/33 for different dunlop tires.

Max pressure?

Agreed but it’s a staring point at least.

Not a good one imo. It's probably a number in the low 40's.

This, but not at all. That number helps you zero.

Because you're riding on the street, not in competition, without tire warmers, I would look for about a 10% pressure rise from cold to hot.
Start with what Dunlop recommends, that'll put you in the ball park. And get a really good, preferably digital, tire gauge.

Here's a tire pressure chart from Dunlop for track riding.
Are you doing proper SM stuff or just street?

Dunlop also recommends tire warmers. So 45 min with warmers than adjust to 30.

Not ideal for street riding as heat cycles destroy them.

 

[dnice]

just street / parking lot stuff. didn't think aboutt trying dirt / gravel with q3s!

would bridgestones bt090 work/fit ?
great sticky tires that don't need warmers; and TD worthy

will the 110/140 17s work for you?

short write up here https://www.petes-superbike.com/14070r17-bt090rg-wr250x-2008-p-1763.html whoops - could not remove ad for "customers also bought" which overrides articel text. fuk comp ad covers text

you could look at other reviews. Ive found people generally like em for grip. 120$ & 136$ front/rear at pete's sbk.
