Normally a 150 tire will go on a rim which is 3‘ or 3.5 rim, but will a 150 tire stretch out to the wider rim?A 160 or larger is out of the question as clearance issues come into play.Rim is 16 x 5.
measure the clearance on the tire that's on the rim at the moment if you have 20mm clearance then you can afford to loose 15mm of it that is each side. as the tire rim sit in the middle so if you have 15mm twice the stock tire is 150. you can fit 180mm as long as your not flexing the side wall of the tire too much. it should be OK but the local tire shop should be able to steer you in the right direction
