Wheel Dish for Wider Tires?

My trusty 700X35mm Clement USH tires are on their last legs so I tried mounting some 42mm Spec Pathfinders on my Norco Search. The Pathfinders seem to fit on the front but are rubbing on the non-drive side chainstay. There appears to be +/-3mm of room between the tire and drive side chainstay. Is it possible to have the rear wheel dished 1-2mm so the tire would fit or am I SOL?

Are you sure the wheel is dished correctly now?

Is the wheel properly dished now? The Norco site says that the Search S1 comes stock with WTB Resolute 42s, so they should fit.

Before you do anything else, remove the rear wheel, flip it around and put it back on (so the axle seats exactly like it did before). Now look at the tire and chainstay. Same issue; 3mm on the NDS? The problem is in the frame, not the wheel. If the 3mm is now to the DS, then, yes, the dish is off and should be corrected (either with spoke dish or moving axle washers).

Correcting frame issues with dish is simply adding funk. Good in many types of music, but not on a bike (although it has been gone many times).

Thanks all! Some answers and clarifications;
- No i'm not sure if the wheel is dished correctly now. I can pop it into my LBS to confirm but will try your wheel trick 79pmooney.
- My Norco S1 is from 2015 and came stock with some Kenda 700X28mm file treads, not the 42mm Resolutes (don't think they even made Resolutes in 2015).
- I sure hope it's not a frame problem in the rear triangle; maybe a trip to the LBS is the ticket.

Do this before you take it to the bike shop. My guess is that the problem is that the spokes have settled (which is common with new wheels) more on one side than the other (again, common because the drive side spokes are at much higher tension than NDS)

Ah. If a bike comes stock with 28s, I'd wager that 42s are going to be really pushing it. Even after you get the rear wheel to sit straight in the frame, you're still only going to have 1.5mm between the tire and the chainstays. Better keep that wheel true!

1.5mm on both sides is very tight. This might still rub even with a perfectly straight frame and properly dished wheel, just from frame and wheel flex under load.

79pmooney has good suggestions to check wheel dish vs frame alignment. I'd be curious to know what the results of this are.

Yes, way too tight at 1.5mm. I'd want at least 4mm each side, and even more room than that would make everything easier. Perhaps 38mm tires would (barely) fit?

I use hex "L" wrenches to check clearances. a 4mm wrench is 4mm across the flat sides, for example.
