With the new tires, the speedometer is now accurate

After dealing with two nail punctures in two tires within three weeks and having one of the patch repairs start leaking, I took it as a sign that it was time to replace the stock Continentals. They only lasted 6,500 miles.

I swapped the 225/65 R17 Continentals for Michelin Defender 2 in 235/65 R17. The ride is much smoother and quieter, but the biggest improvement is that my speedometer is now accurate.

Previously, with the 225/65 R17 Continentals, GPS-based apps and roadside radar detectors showed that when the truck’s speedometer read 65 mph, I was actually traveling at 63 mph. This discrepancy also led to the truck overreporting fuel economy and mileage.

With the 235/65 R17 Michelins, the speedometer now aligns perfectly with other measurements. I am curious if the Maverick was actually designed to use this tire size or if the smaller stock tires were intended to improve reported mileage.

I have around 24,000 miles on my current factory tires, with an estimated 6,000 to 10,000 miles left. I’m looking for a good replacement and was wondering if your new tires offer better grip. I don’t feel very confident in high-speed corners with my stock tires.

It’s said that the Michelin Defenders have excellent wet and dry grip. To me, the most significant aspect is their 80,000-mile warranty. But I haven’t been cornering the Mav at a lot of speed lately.

I still have the stock Continental tires, and they have been accurate when passing speed sensors. However, I got a razor blade stuck in my back tire and had it patched. I am worried it might start leaking like yours did.

Every vehicle I have ever worked on or drove has a little report. The police interceptors with their certified calibrated label on the cluster were the only ones that were completely off-target. It really was that bad.

My mav is being built next week, but I have a mini, and it’s usually 2 mph slower than everything else.

My R57 overestimates speed by 4% from the factory. It’s probably helped me avoid a few speeding tickets, and my 0-60 time is actually quicker than what the magazines report.:smile:

My B48 is here, so I suppose you can add two more manufacturers to the list.

It’s fairly common for speedometers to read slightly high, I have noticed this across many vehicles.

It is illegal for OEMs to underreport speed.

Thus, the majority exaggerate their level of safety.

It’s your business what you do with your machine after it leaves the lot. :sweat_smile:

That is not totally accurate. Per federal law, a deviation of plus or minus 5 mph at 50 mph is permitted.
