Unfortunately, this is where you may come unstuck…literally!
No tyre manufacturer recommends that you mix tyre brands on the same axle. That they must be of exactly the same size is obvious, but it’s equally important that they are of the same compound and tread pattern otherwise they may react differently when under stress - such as cornering - and adverse conditions - such as a wet road.
In your case the tyre is nearly new, but you can see how even replacing the punctured tyre with a new Dunlop Maxx could create a performance difference if the other Dunlop Maxx was down to, say, 3mm.
This is what Dunlop themselves claim about the ‘superior’ compound and tread development of the Sport Maxx. It’s unlikely that they would accept that another brand would match its performance characteristics.
The Dunlop Sport Maxx is developed using motorsport-derived polymers that react to the road’s surface, maximising road contact and grip. This adaptive compound technology not only improves grip but delivers precision and enhanced safety whilst driving.
The well-thought design of the Dunlop Sport Maxx is the reason why this tyre performs so well. Enjoy enhanced cornering control due to large shoulder blocks enhancing stability, allowing for a smooth and precise drive on the straight and a bend.
The Dunlop Sport Maxx provides shorter braking distances even whilst driving at motorway speeds. The short braking blocks increase contact with the road under braking force to deliver quick, safe braking at high speed.
