300/35-18 on a 2008. However your bike is a left side drive… are you sure it’s a 2008? The mastiff was last made with the LSD transmission in 2006. Specs say 300 on the rear either way LSD or RSD. Go with the 300.

In documents what i got this is year 2008, but right now there is 250 tire on rear
I looked at your picture and it looks like a 250. But the specs say 300 rear.. for 2005 and newer. Here’s the simple truth of the matter. If you have a 250 on the bike now. That’s what you need to buy. A 300 will NOT fit on a 250 swingarm/ rearend.

So it seems that in 2005 the BigDog Mastiff was built with a 250 rear tire. In 2006 they did major changes to the mastiff one of which was upgrading to the 300 rear. Again if you have a 250 on the bike currently that’s what you need to order. The good news is… they are a hell of a lot cheaper than a 300.

I concur. Bike looks older than 08. Im thinking 03-04? Appears to be a 250 rear.

Anybody got manual for earlier big dog mastiff 2004? Im trying to search it but nothing....
In the top right corner. Hit the search engine. Search Dropbox’04 mastiff. Should pull up old threads. HMAN has a link there. Open the Dropbox and you will find all the manuals there.
