And a road froce balance is worth it weight in gold. It can really make a big difference especially on a high end car. Even if you don't routinely take it to warp factor 5.It's very noticeable at even 120 kph. I have personally done both and let me tell you, what a difference. Don't let the shops " we have a really good balancer" reply fool you. There is no substitute for a proper road force balance done by a tech who has good equipment and knows what he is doing. A proper job takes some time and effort. Some techs will not put in the time to do it right. I have many friends with shops. I did a barter deal with one friend. He did work on my Expedition and I did the work he needed on his boat. He had the new " great tire balancer" that he paid big bucks for blahh blahh blahh on he went lol. It was not a road force balancer but his speech convinced me.... yeah. Well off they came for a road force balance after a few hundred K's on my other friends Hunter Road Force machine. No comparison. I will never go for a regular balance again.
I'll need some serious time to put together an all encompassing tire thread. Much more to it than most people think. I thought I knew quite a lot a few years ago but there was soooo much I did not know... and am still learning. Might do it in pieces , road force balancing video, tire removal and mount, proper techniques that techs should use etc.
