Check your tire size on your e300 and make sure you dont have a older version that had the 3.00-4 tire because this is smaller and is what all newer e300 scooters come with, just not as good of course.

This new 2.50-4 tire (8" x 2-1/2") fits many scooters, hand trucks, dollys, lawn mowers, and wheelbarrows that use a 4" rim wheel with an 8" tire.
Please check the sidewall of your tire - if it says "2.50-4", "2.80/2.50-4", or "2.80-4" then this tire will fit. If it doesn't please browse our other listings to see if we have the one you need - we have 3.00-4 and 200x50 sizes.
