Why are you running such skinny tyres on your 7" rims. According to the "Tyre & Rim Association of Australia" the P175 tyre width is permitted on a 7" rim in 60 profile sizes & below. You are running an ILLEGAL combination. Ever wonder why some things are ILLEGAL? I wonder if it is because it is UNSAFE.

I had always thought that the purpose of wide rims was to allow wide tyres, yet the P175 tyre is both legal & safe on a rim right down to 4-1/2".
I run 185 x 60 x 13" on the front with 5-1/2" rims. This tyre is 552mm in diameter which is the same size as the original [stock] tyre. This means no scrubbing on the inner guard when turning.
Your tyre is nominally 584mm in diameter & i suspect that it rubs sometimes.
I also run 205 x 60 x 13" on the rear on the same 5-1/2" rims. It seems to me that you could have a better tyre selection available to you if you used smaller rims instead of needing pizza cutters to clear the guards.

Motto Think twice, act once.

P.S.
The 185 x 60 x 14 is nominally 578mm in diameter & i wonder if they rub the inner guard too. This tyre was DESIGNED around a 5" rim, as was your tyre.
