The correct pressure is crucial when you carry the weight we do day in day out when I put cheap tyres on the van the under steer was laughable,we get so much wet weather here you can’t put a price on it.
I’ve always used budget tyres for the van, and as said, only 2 new front tyres in 4 years.
Never had a problem with grip, because I don’t drive it fast, and with 750l onboard, the weight of the van keeps it stuck on the floor.
Obviously I fit commercial tyres, but always budget ones. Rears are still like new, and they’ve been on there since 2013.
There is absolutely no way you’re going to notice any difference in performance in a van when poodling around with a tank full of water. None what so ever. I have never ever had the ABS cut in on wet, cold, or icy days. Because we just don’t drive vans fast enough. We window cleaners drive them sensibly knowing we’re full of pure water. Plus, it’s a van! It’s not for racing around.
Sure, premium tyres might last longer, but that’s about the only thing you’re going to gain.
Unless you drive very fast and brake very late in the wet, you are not going to know what rubber is under each corner.
Bet you a blind test would prove that.
The car, that’s a different story, as i drive it quick. So the rubber needs to meet that demand.
