Is there likely a problem having a Falken one side and a Dunlop the other at the rear? Sizes are correct and both brands have a very similar tread pattern - front has Dunlops both sides. Wheels are 20" Sentas -2006-7 XK X150.

 

It's generally not recommended, but doesn't appear to be illegal. You might want to check that, reading other forums people have been stopped by the police for this, though apparently it hasn't lead to anything.

I wouldn't do it, even if only for image reasons.

From a legal point of view its recommended to have the same manufacture however not compulsory in Vic, having said that the profile (sidewall) and width must be identical from left to right tyre.

The main issue that will arise from different manufacture will be tyre grip which in turn have a bearing on the vehicles's braking and handling .

 

Here in Germany it is not legal.


But even when it would be legeal, I would never drive two different tires on one axle, because tires have very different emphasis

 

I've never heard where it would be illegal. That's crazy. Maybe 'not recommended', but to say "illegal" indicates possible jail time. Maybe a 'violation' instead? Two of the same brand tires with different wear patterns and tread depth would be just as dangerous as different brands. Maybe more so.
Anyway, just because tires have the same SIZE does not mean that they are the same DIMENSIONS. You'd have to measure the roll-out, or "rolling circumference", but it's not directly related to the Diameter, which is one of the more important measurements for matching tires.

 

Sorry, I was wrong, in Germany it is allowed, but not recommended.

 

In my years of experience with Hi-Performance cars, the rule has always been DO NOT MIX BRANDS OR TYPES OF TIRES. This is because there may be different performance characteristics, between brands and types. Mixing them may change the performance of the car drastically.

 

I had a major brand tire shop order the wrong compound of tires and install them on my car.

I had all season tires all around when I brought it in for new tires.

Well...apparently I left with all seasons up front and summer tires in the rear.

First cold morning I went to make a turn onto another road the front quite willingly took the new path, the back tried to stay the direction it had been going.

Fortunately the road I was turning onto was two lanes wide in my direction; at less than 20MPH my car was sideways across both of them.

Now I walk around and look at my tires after getting new ones installed.

Its really only a safety issue if you don't expect it and can't control it. I'd rather have the maximum out of my car and match up tires for the best possible performance.

Just having tires of different ages can change the balance of available grip in a corner.

 

I don't mix side to side but have mixed front to rears. It also depends on what type of driver you are and how do you want to use the car. If you are a week end cruise driver and follow most of the speed limits then mixing is not much of a problem. If you want to be an F1 driver then get the tires you need . I prefer to go with the mix of a performance all season tire. It suits my needs .
