Default tire compound 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!

Default tire compound

The higher the shore number, the hader the tire compound.
33 shore are softer than 40
Its kind of difficult to say what shore you will need without knowing the condition of the surface.
Smooth, course, it is a little difficult to say.
Usually a safe bet would be some where around 37 shore<not the softest, not the hardest>.
Soft tires will wear out faster than the harder shore tires

When I raced 8th onroad a while back we always used 40 shore front and 37 rear. Sometimes I ran the same shore all around. After a while when the tires dried out I hosed them with WD40 and used a rag to soak up the excess. Believe it or not this does help restore traction. Don't forget to use the 7mm split between the front and rear tires. There was also a trick to use a different pulley up front if you don't have access to a tire truer however I forgot how many teeth difference between stock.

thanks for the replies guys...the surfaces will be pretty coarse. Only one surface is fairly smooth.
So, I am thinking of 40 front and 35-37 rear? sound ok?
