I wouldnt worry.... I dont actually
Cheaper tires can be noisier as well as less grippy
My engine drowns that out.
Worst tires i ever had were expensive pirellis that was direct replacemen for wht was on the car
Best gripping were a set of hankooks - lasted less that 12k though
Vans running on some franks fast fit 45 quid specials van weight rated. Neer found the grip limit as i know im not colin mcrae...... They have done 35k without issue so far and look to have plenty life in em conti Van contacts that came on it did 45k.
Id be more worried about a tires age than its brand!
Running remoulds on the jeep. Mainly because i trash more tires with rock slashes than road damageand 47quid is much more managable than bfg 150 quid..... Bfgs came on the truck and didnt fair much better
