Pictures can be deceiving. We have a 14-1/2 year old Maltese that weighs 5 pounds and is blind and deaf. I don't want her to be overwhelmed by a lot bigger dog. We don't do this professionally, just want to maybe help out, which is why the questions.
It would seem with the volume of "old" twins out there that they would make an adaptor to plug and play to change over to the new one. I would buy one in a minute if there was an adaptor, but I am not going though rewiring.
I am old and have a LOT of experience on off roading and tires. I have posted this before.
Tire, pressure and wheel thoughts
It seems to me that there are a lot of questions on tires and wheels. I have never worked in a tire shop, but I have bought a lot of tires, wheeled off-road for over...
Yesterday we did Devil's racetrack, which is about 60 miles west and north of Moab. A difficult trail with amazing scenery. Long day, left Moab at 9 am and got back at 7 pm.
On road not a lot of difference, but stay with Load C. Off road go with 17". More sidewall to absorb rocks, also give you more room when you lower pressure before the wheel contacts the ground. KO3 is a great all around tire, I would go with that.
