Highway summer tyre for SUVs and light trucks

The Starmaxx Incurro ST450 H/T is a summer tyre built for highway use on SUVs and light trucks. Its asymmetric tread pattern and heat-resistant compound deliver dry and wet grip, while four circumferential grooves clear water to resist hydroplaning. The reinforced internal structure maintains shape under load for stable handling. A black sidewall completes the fitment.

Drivers wanting quiet summer highway performance

This tyre suits owners of SUVs and light trucks who drive mainly on paved roads in warm conditions and value low cabin noise with responsive steering. It is not for buyers who need winter traction, off-road grip or run-flat capability, as the summer compound and highway tread design do not address those requirements.

235/55R18 100V XL sizing with 320 AA UTQG

The tyre fits 18-inch rims, carries a 100 load index and a V speed rating up to 149 mph, and uses an XL load range for extra capacity. Overall diameter measures 28.2 inches with a 235 mm section width and 10/32 tread depth. The 320 treadwear grade and AA traction grade indicate expected wear and wet braking performance.

Questions about this item

Does this 235/55R18 tyre fit my 18-inch rims?

Yes, the 18-inch rim diameter matches the tyre size exactly, so it will seat correctly on your existing wheels.

How does the summer compound and asymmetric tread behave if I keep my older all-season tyres on the other axle?

Mixing summer and all-season tyres can create grip imbalance in wet or cold conditions because the summer tread and compound are optimised for warm weather only.

What should I check to confirm the Incurro ST450 H/T is performing correctly after fitting?

Verify even tread wear across the 10/32-inch depth, stable steering response from the asymmetric pattern, and low cabin noise on highway runs.
