My fiesta car tyres are a 195/40/16 standard size but can I use 195/45/16 tyres what's difference is it the profile that's all are they compatible? Thanks
https://www.tacomaworld.com/tirecalc?tires=195-45r16-195-40r16 The 45 & 40 are profile height of the tyre sidewall,this number is always shown as a % of tyre width,so 45, shows that the aspect ratio of the tyre is 45% of the width.
Safer to say no. Unless Ford day you can, fitting the wrong size would potentially invalidate your insurance. This change would mean your speedo was out. It’s a bit early, but I think you would be going faster than the speedo says. Might work it out later if you decide to fit them. As it’s a change of size you would need to fit them in pairs across the axle.
You would be a tad faster, in my link above it shows the speedometer difference,etc. Still too early for me. https://www.tacomaworld.com/tirecalc?tires=195-40r16-195-45r16
I worked it out on the back of an envelope and got 2mph at 60, happy to see I can still remember something
If you do change profile, you will need to change all 4 tyres, not just an axle pair. The wheel speed sensors / ABS module will clock up a rotational difference between the axles & probably pop up a recurring ABS fault warning.
You'll be fine, gazowl. Out of interest why do you want to change the tire size are they cheaper or do you just like the look of them better?
I believe you can change the tyres to whatever you wish as long as the overall diameter of the wheel and tyre stay the same. Plus you would need to inform insurers of the change, they may want a charge for this !
If my tire sizes are not correct, I find the 4 wheel drive keeps engaging and disengaging and it feels as if I am driving on a concrete road, smallest tires must be on the front, so if I renew tires new always fitted to rear. And not talking about a different tire, just the wear from driving. It seems the 4 wheel drive is triggered by the ABS so it would seem likely even without 4 wheel drive it could cause a problem. Years ago I fitted paddles to a Landrover for off road use, with smaller wheels to take larger tires, but today that's no longer an option.
