Summit Ultramax A/S 2.0 All-Season Tire 225/50R17 94V for BMW

At the core of the Ultramax A/S 2.0's wet-weather capability is a silica-enhanced tread compound that grips slick surfaces more effectively than conventional rubber while simultaneously lowering rolling resistance. Four wide circumferential grooves run the full circumference of the tire to evacuate water rapidly from the contact patch, reducing hydroplaning risk at highway speeds. The non-directional tread design adds mounting flexibility — these tires can be rotated in any pattern, simplifying long-term maintenance on your BMW.

Summit engineered the Ultramax A/S 2.0 with two structural upgrades that matter in real driving conditions. The jointless bead cover wraps a continuous spiral steel band around each bead, stiffening the tire's foundation and translating driver inputs more directly into steering response. The higher sidewall turn-up reinforces the sidewall from the inside out, adding meaningful resistance to lateral flex during cornering — something BMW's sport suspensions will reward with sharper, more communicative handling.

A variable pitch tread pattern staggers block sequencing around the circumference to break up harmonic resonance, keeping interior noise levels low and preserving the composed, premium character BMW cabins are known for. For owners who want a dependable all-season tire that earns its place on a performance-oriented car — without the premium price of OEM-spec rubber — the Ultramax A/S 2.0 delivers practical, year-round capability with the structural integrity to back it up.
