Upgrading from 215/75R17.5 to 235/75R17.5 Tires on Car Hauler

Question:

Good morning I have a equipment car hauler and my current tires are 215/75/17.5 and the rim size is 17.5 x6.75 the issue Im having my tires keep blowing due to weight I put 17500 on each axles my axles are rated 20k the tires are rates 4500 dual. My question is can I upgrade my tire size with the same rim I want to get 235/75/17.5 to add a better weight rating. And will the spacing be to close to each other. Thank you for your time in advance.

A tire like the Provider 235/75R17.5 Radial Trailer Tire # P35175 will fit your existing 17-1/2" x6-3/4" diameter rims. However, the clearance is something you will need to measure and see for yourself based on your trailer setup. This tire has a section width of 9.17" and an outer diameter of 31.38". Compare this to your current tires to see if you will have enough clearance once you replace them.
