Should I only change front time of different brand?

After being out of the hobby for over twenty years, I come back and find that conventional wisdom is strongly suggesting changing both tires at the same time. Now I didn't on the last tire (replaced due to holes, not wear) and at the price of some of these tires that can be a large pill to swallow. But ideally, do both and keep them in the same family.

I suspect the "replace both at the same time" mantra comes from the tire industry.

My Triumph T100 Bonneville came from the factory with a Metzler bias tire on the front and a Metzler radial on the back. (??)
I really didn't notice the difference until the time came for new tires and I started reading what was on the sidewalls.
The bike rode and handled fine. I had a set of Bridgestone's fitted and the bikes rides and handles exactly the same as before.
I'm not a hard rider, but I enjoy, shall we say, "spirited" riding

I looked around on some other forums. Bias ply rear and radial on the front is pretty common OE (especially cruisers, Triumph does it a lot). People report that mixing bias ply and radial on cars is disastrous, but not on motorcycles.

Conventional wisdom I've always heard is that mixing is a no no. This sort of changes that....

Interesting. I have to admit, my reluctance to mix types comes from cage experience. I guess I always assumed that mixing them on a bike would give equally bad results (and, as you say, it was the conventional wisdom).

If I'd known about this a few weeks ago, I definitely would have gone with the BT-45 as my new front tire.

in car - tires **should be** the same on same axle. so you can have 2 tire types on a car.
The reason is for braking and acceleration, in emergency braking, you want tires on same axle bite the road of same force.

there are a lot of misconception when i change tires of my son's car, they say put a new pair in the back. It does't make sense, the front pair should be the better one, for braking. if one tire would blow up, I prefer the one in the back blows up since front tires provide directional control.
