Got the new 27" zillas on 14" STI rims for my RZR today so did a nice upgrade on my daughter's 300sp. Was told 25's would probably fit with minor trimming. Took my stock RZR tires/rims and mounted them on the 300 with no clearance issues(close but work without trimming). We're headed out next week for 4 days of riding so I'll post an update if we have any issues for those looking to get their 300's up without lifting!

 

i had to trim our 400 HO(same as the 300 set up basicly) when i put the 25" swamp lites on. it was the rear wheels that ws hitting. i think it all depends on how much tread you have and there was alot on the s. lites.

 

Would love to see some pics, when you have an opportunity!!

 

I'll get some pics in the next week or so. We'll be out at the cabin riding so should have plenty of photo ops.
