Hello , I install my own , use plastic jug cut up for rim protectors, , heating tire in the sun helps,
The worst part is breaking the bead on the old tire, finally borrowed a friends manual bead breaker, piece of cake with it,
You may need C clamps to hold sidewall in the narrow part of rim starting out, You need to balance it, I used
tire weights,with the axle on some jackstands , Dynabeads work too, I use dish soap with water to lube rim and bead, I put the tire on 2 4x4s to protect brake rotor and rim , Have changed 4 DS tires now, the first was the hardest.
