First, the horse in question - 6yo, gelding, 16.2hh, Latvian Warmblood, light draft type. They are traditionally used as carriage and allround horses here. He has been introduced to driving at age 4, and since then he has been pulling some logs and light constructions from logs and tires, and we also often ground drive. He's a bit downhill in this picture (July), but he has leveled out since then.

Since it has been snowing, I plan to put him to a sleigh soon, and it will be his first "proper" pull ever. When summer comes, I hope to start driving him in a carriage or a cart, and I have been eyeing this one:


I have, however, heard, that carriages with wooden wheels are heavier and harder to pull, especially, for inexperienced horses, and that driving should be started in a cart with rubber tires. The problem is that around here such wheels are either only on fugly working carts, mostly half rotten, in which I don't want to invest, either on super expensive marathon carts that are simply out of my reach.
So, experienced drivers - would it be a good idea to get this carriage? The roads around our barn are mainly flat dirt ones. I am myself a beginner driver, but I plan on getting some more driving lessons in a local driving barn before I harness him to the carriage.
