Tyres for an Oxford Allen Scythe

Do you normally fit 195/70 15 tyres? The tyres would fit, BUT the 195/65 R15 tyre is actually smaller than the 195/70 R15 tyres. The rolling surface, the area with the tread marks on, is shorter on the 65 size tyres. This will make your speedo read at the wrong speed and might affect the handling.
This is what the numbers mean. 195 = width of the tread across the tyre in mm. 65 = height of the side wall as a percentage of the tread width, (65% of 195mm). 15 = diameter of the wheel rim in inches.

typo there same tyre sizes
geerally on all cars
tyre placard sticker somehwere on the chassis
or glove box owners book
says what size tyres are suggested

you don't remove tyres with an allen wranch... correct your question?

commenting on fuel consumption is like asking "how long should a piece of string be?". The variables to be considered are tyre pressures, size of tyres, width of tyres,tread patterns,wheel alignment, loads carried by the vehicle, climate temperature and conditions, driving techniques,traffic conditions, speeds travelled, use of gears to maintain correct torque range from the engine, electrical loads required from the alternator and terrain conditions
Some of the things that you can do to improve fuel economy include selecting neutral when stopped as this reduces the load on the engine at idle and the fuel setting is less, having your foot on the clutch loads up the thrust bearings on the crankshaft. An automatic is always trying to drive when stopped so by placing it in neutral when stationary allows the engine to idle at a lower fuel setting. run on standard size tyres and increase the air pressure around 4psi make for less rolling resistance from the tyres so the economy will be improved. Carrying as little as is necessary, (That includes driver and passenger weights) reduces the load on the engine--more economy.Using a cruise control were possible or reading the traffic conditions so that vast speed changes are required less so will improve economy. experiment with different octane rated fuels ( be wary of e-fuels) While you may be reading manufacturers sales rubbish about the expect fuel consumption of a particular vehicle remember that it is sales talk as economy is heavily dependant on engine/vehicle design and driver technique. Basically there is no one single thing to consider for fuel economy but ultimately it all comes down to the driver.

If the tyres are slicks on one side and new tyres on the other this is a possible consequence. Check that the tyres on either side are of identical profiles and sizes with approx. the same tread wear.

The wheels could have been changed on the car from the standard original factory set and hence the tyre size may not be the standard factory original size.
The size of the tyres on the vehicle now is moulded into the side wall of the tyres and is easy to read.
Check all 4 tyres because larger size tyres may have been fitted as a pair to the rear.

The size might read - for example 245 45 18 or 235 45 17 (there are a huge number of sizes for each model of tyre).

The first 3 numbers are the width of the tyres in mm eg 225 mmm or 235 mm and so on. The second 2 numbers are the tyre profile size or ratio (which can be 70 65 60 55 50 45 40 and so on. The third number is the wheel diameter size. If you have 18 inch wheels on the car the tyres will read 18 or if they are 17 inch wheels the tyres will read 17 and so on.

replacing one is ok but replace two minimum to create even wear on the tires

It depends on the specific model, but I have found a website that should help:

The wheels are held in place by an allen screw in the centre hub, the square pin which is usually sticking out also needs to be removed. If the centre hub is stuck fast, use a plastic hammer to strike the inside of the wheel to drive it off the axle until you have a gap to get a puller in. The centre hub should be a nice loose fit when you reassemble it and use a decent grease on it.
