Trike Wheel question

[Big Coup]

Need some consul... Looking to put some new wheels on my 2015 Trike. The question is, what is the largest wheel I can put on the front and rear of the Trike, without major modification to the trike? Thanks in advance!

When you say "largest",are you talking width or diameter? On the rear,you can fit anything from a 15"-20" diameter wheel and 6.0"-6.5" width.(stock is 15x5.5). On the front,you can probably get away with a 21" wheel without needing custom triple trees. Will need a different fender,though. Personally,I wouldn't run anything larger than an 18" front or rear wheel but that's just me. Our trike has 17x7 rears and 18x3.5 front.

I run a 21 on the front of my 13 TRI and had no problem with the fender. Bolt on job.

Thanks,I knew a new fender and trees would be required to run a 23" wheel but wasn't 100% sure about a 21". That's why I said "probably".
What kind of load rating can you get on a 21" front tire?
