Does tire size affect the braking system?

My car (Toyota FJ Cruiser) has stock 265/75R16 tires. The closest size for winter tires i could find for it was 245/75R16. As I used the tire calculator thing, it said i have 3.8% difference in my speedometer. Is that a big deal for braking system or anything else?


Absolutely. It has to do with the friction on the size of the surface area of the tire hitting the road.

The tires are actually smaller. Tire width in MM / Aspect Ratio / R Radial- Rim size . This has everything to do with weight. Remember an object in motion tends to stay in motion unless acted on by an outside force. The more weight the more force needed to stop and start the tire rotation.

as long as u have the same size all round u shouldn't have a prob at all u will get probs when there r diff size tires front 2 back coz it will mess up wheel speed sensors 4 your abs other then your speedo being out u shouldn't have any probs at all
