Tires and fenders

[katblue3]

I turned a 2013 sportster superlow into a trike (DNA axle) rides great but the front tire is a concern. factory tire is a 120/70-18 and i want to replace it with a rear tire (more rubber, more miles) but I can't find any rears that size and I am unsure how far off original spec I can go, have found a 120/90-18 but I am unsure if it will fit my wheel (stock) rather not buy the tire then find out it will not fit. And I am finding it hard to find some decent fenders for it that are reasonable priced the ones that are available in the US are running $580-$700, that's ridiculous for a couple small pieces of fiberglass. Currently i'm using a trailer fender cut in half, it works, cost only about $40 but not real pretty. If anyone out there can school me on alternate tire sizes and tell me where I can get decent fenders at a reasonable price I'd appreciate it

Tire size

A 120 tire on a Sporty Trike sounds good to me (being a sportster rider from the '60's) . How many miles on the tire you have on now ? Did you put a steering damper on ? You should consider it (keeps wheel shake to a minimum going over rough roads) . I have one on my 2 wheel Sporty and 1 on my 08' Street Bob trike conversion (19" front tire) . As far as the fenders go I think you made the right choice for now using a trailer fender . You will have plenty of time this coming winter to make up your mind on what you want to add/change on your trike . If this is your first trike watch those turns .

Ride it !

Your bike's front wheel is an 18x3.

A 120/80-18 rear tire will fit your rim but it will have a slightly bigger circumference, so you have to make sure it doesn't rub the fender.
