I'm guessing that the rear tyre didn't rub when it was a 32 and only rubbed when you changed to a 35?
In that case, to make sure, you could:
Take the 32 tyre off your front and put it on the back wheel with mudguard.
If it does not rub then that's the issue (35 is too big with mudguard).
You can then either buy a 32 and have it back to the way it was. (32 on front and 32 on back).
Keep the 35 as a spare or another bike or sell or whatever.
Or maybe the 35 would be fine on the front with the mudguard?
Either way, sounds like sticking to the 32 will solve the rubbing?
