Touring with different tire widths
I've got a very small punctured sidewall on my brand new rear tire (Pasela tourguard 26x1.25) from an off-road excursion.
The LBS advises replacing it. If so, I'll go with Specialized Nimbus Flak jacket which is 1.5 and keep my tourguard up front.
Is there any good reason not to do this ?
Also wondering about just repairing the sidewall for a weeklong trip.

You're fine. the 1/4" difference isn't enough to affect anything, provided there's enough clearance under your fender for it.
The geometry nazis might claim it will steepen your head tube angle and make steering more twitchy, but the result of this change will be about .36 degrees, which can have no discernible effect on anything.
as for repairing it, because the threads running through the sidewall support the tension of the tire stretching over all that air inside, It would be difficult to repair it without a large sewing machine and a rubber factory. If it is small, a tear can be booted with a dollar bill, or a few layers of duct tape between the tire and tube. Ride on at your own risk!
I think the main idea here is that you need a new tire anyway, and this bike shop sells them.
