Up until recently, tyres never really bothered me - I knew some were grippier than others, but other than that I didn't have a clue about all the other specs on them - load bearing, speed ratings, etc. Just things that had never entered my mind - I'd looked at speed ratings as "well I'm not gonna be doing 149mph, so I don't need V rated tyres", but then you realise that the higher the speed rating, the better the tyre is constructed, which affects it's quality at any speed, not just maximum. Same with load - sure, I could get an 89 rated tyre, which will support 580kgs (and my car exerts about 526kgs per tyre) - but then you realise that a higher load rated tyre, such as a 93, will handle the weight, fully laden or not, at any speed better than a lower load rated tyre.

So even if you aren't gonna be driving the doors off it, a 93V is going to be all round better than an 89H.

I can't afford the absolute last name in tyres, but I will now always go for the best I can afford, rather than look for the most affordable. I'd rather spend double on tyres and nothing on engine mods, than spend £x on making it faster and buying lesser tyres.
