New tyres - first observations.
I used farbic tyres for 1500 km. In cold, wet days they were not very trustworthy - slippy - especially on turns as I am taller and more heavy then average rider. I decided to change them for this season.
After some conversations with more experienced bikers - I bought Michelin Pilot Street. In present crazy days change includes self umount/mount practice what improved by garrage by a few new tools ;-]
First observation - as I have alloy wheels - is problem with balance of freshly changed tubed wheels. Up to tyre service I need to ride a bit to fit new tire and tube inside well and then I should deliver whells again for balance tuning. Hmmm...
As a result so far I feel some shaking at 40-50 km/h. Above it stops. So defenetly I really need to visit service again after another week of driving.
But traction looks much better so far. I do not feel sliperry so far. But what surprised me - TCmax looks a bit more effective in speed. Usually up to my size I could reach 80-85 km/h - up to road conditions. So below formal max speed. Now it is some 5-8% more.
So the most unpleasant part of alloy wheels is its balance. Or... service I choosed made bad work. First time changed tyres on motorcycle alloy wheels. Has anyone done that?
Michelin Pilot Street & Pirelli Angel City are good tyre options for the TC Max.
I take it you had the new tyres fitted at a tyre centre so my question is... Did they balance the wheels after fitting the new tyres or tell you to bed them in and bring it back for balancing?
1st service said they could not balance them and I should be back later.
But I also visited another service which just said they never balance such wheels but they work was done much better - my front wheel works almost fine after their job.
And in fact - original fabric wheels are also not balanced. Maybe it is the way it works.
It doesn't make any difference if your wheel is cast alloy or spoked as the tyre still needs to be fitted correctly.
Most decent tyre manufacturers add a paint dot or similar to the sidewall of a tyre to indicate the balance point. This needs to be lined up with the valve for the wheel/tyre combo to have primary balance. Further balancing using a static or dynamic balancer may or may not be required depending on how well the wheel/tyre combo is balanced.
From what you've said it seems that the first company did a poor job and the second refitted the tyres correctly but lacked the adapters to fit your wheels on to their balance machine.
