Default Tire question

Hey all...new to 1/8 onroad and looking to get into it. I was browsing tire selection and noticed that each tire is followed by a corresponding #. My question is the higher the # the softer or harder the compound..

I will be p-lot racing mostly w/friends running a MRX-3 or MRX-4..so which compound would you all recommend..

thanks!

The number you're referring to is the shore or durometer rating. The higher the number, the harder the tire, which normally equates to less grip, but that's not the end of, or the entire, story when it comes to foam tires.

The tire that's going to work best depends on the surface you're running on, your setup and speeds. Run too soft of a tire, and they won't last, run too hard, and it'll never hook up.

From a money standpoint, running on a parking lot track, start somewhere in the middle-high shore rating, and go up or down from there depending on tire wear.

You'll also find harder front tires compared to the rear will balance out tire wear. Ideally you want all 4 tires to wear at about the same rate.

thanks for the info. I am looking at 38-40 front and 32-36 rear as a starting point.

Are certain manufactures tires better than another as far as wear/durability
