You really need to read the rules more closely
Unbelievably your 75mm claim is correct but this is combined with no more than 50mm suspension and added to this no more than 25mm tyre. this gives you 50 + 25 = 75
Also in regards to your tyres sticking out beyond the guards and being illegal it also states that the wheel track shouldn't be any more than 50mm from standard, this I'm sure you have well exceeded
jump over to 4wdaction mate, you'll fit in better there I assume
3.4 Wheels and TyresThe overall tyre diameter can be increased to allow an increase of 7.5mm in vehicle height
for passenger vehicles and no more than 25mm in vehicle height for four wheel drive
vehicles (typically MC ADR category).
Tyres fitted to off-road passenger and light goods vehicles (MC, NA, NB ADR category) must
not be more than 50% wider than the vehicle manufacturer’s widest optional tyre. Tyres fitted
to passenger vehicles must not be more than 30% wider than the vehicle manufacturer’s
widest optional tyre.
The rim width must match the recommendations for the tyre fitted.
The tables of original tyres with the maximum allowable tyre and rim sizes in Clause 4.2
Non- Standard Tyres and Rims in the NCOP are applicable.
The wheel track of off-road and four wheel drive vehicles (MC, NA, NB ADR category) must
not be increased by more than 50mm beyond the maximum specified by the vehicle
manufacturer for the particular model. The wheel track of passenger vehicles, including four
wheel drives or all wheel drive vehicles certified as MA ADR category must not be increased
by more than 25mm beyond the maximum specified by the vehicle manufacturer for the
particular model.
The wheels must be contained within the bodywork or mudguards (including flares) when the
wheels are in the straight-ahead position. Adequate clearance must be available between
the tyres and the vehicle bodywork.
Speedometer accuracy must be maintained for the selected tyre and rim combination to
within the degree of accuracy specified in ADR 18 where applicable
