Ive been running a 5 door 97 diesel Suzuki vitara here in the UK for some 4 months.
The previous owner had 215/45/16 tyres on it. The first thing I did apart from repair the crash damage(another story) was to fit 185/75/16in 8ply commercial tyres, these are for Ford Transit vans and can be run up bto 60 psi.
However I run mine at 40. They have a much lower rolling resistance that the original ones and its always been the case that skinny tyres are more efficient than low profile wide section ones.
If your driving for economy, then you dont need lots of grip so skinny tyres will do just fine.
Im getting for a kerb weight of 1.5 ton 40 mpg running around, 46 on 70/30 motorway/urban stop start driving, and expect to get 50mpg on a steady 55mpg on motorway use.
thats using BP ultimate50/50 with bio diesel.
The next step isto fit a temp controlled electric fan .
Have the fan but havnt found the electronics to vary the speed dependent on temperature.
At the moment its all or nothing!!.
Keep us posted here for your thoughts.
Dont buy the low profile wide tyres. They eat energy.
