Yup, I'd agree with that. I bought a set of used Kumhos last year & none of them were balanced or gave me any reason to believe they should've been. The new pair of Toyos of just got (to replace the fronts which a bent tie rod - on an XJ - knocked out in 150 miles) have more weights than I like to see. However, it's not the number or size of the weights, it's how easy the tyre is to balance, e.g. if it has to be moved round on the rim & the whole exercise began all over again, chances are it's not a premium brand.
I had intended to get Kumhos again but there aren't any in the size I wanted. I'd all but decided on Toyos when I read a particularly favourable recommendation on this very forum - but, of course, nothing's that simple: I'd always understood that Open Country was a tyre, but it's not, it's a whole range, so I didn't get AT3's, the Winter tyres I wanted, but ATPluses which are "all season" albeit "M&S" which, far from being a budget alternative to the Nexians actually cost 1/2 as much again. Whether that is a size thing or pricing strategies in different markets I really don't know but next time I'm going for Yokohamas, simply because they are the only Winter tyres available in the size - apart from BFG's, & I'm simply not prepared to spend that sort of money (far more than the purchase price of the vehicle)
The KJ on the other hand came on BFG A/T's, which seem to have been fitted when it was new. No complaints, but they are starting to show their age although probably not much more than 1/2 worn. I think they're a bit too aggressive for a largely street driven KJ but a pair of nearly new ones, on much better rims than mine came up at too good a price to let go - so I guess I'm stuck with them, as will undoubtedly outlast the KJ or, at least, my ownership of it.
