That may work in the US but in the UK one defective tyre negates your insurance, and no insurance means your car is impounded. Traffic cars are fitted with ANPR (Automatic Number Plate Recognition) which is connected into the various databases for insurance, testing licencing etc. There are cameras on gantries in cities and busy roads. Flag up and you are stopped.
Each defective tyre gets you 3 penalty points. And penalty points stay on your record for from 4 to 11 years. 12 penalty points on your licence means you are banned from driving. Driving while banned can mean jail time.
Much cheaper here just to replace your tyres when they wear out!

In Germany only the tread depth is limited by law. It has to be more than 1/16" (1.6mm).
Summer tires should be not older than 10 years, tread depth 1/16".
No information for the age of winter tires, tread depth should be more than 5/32".
Tires at trailers are limited to 6 years, tread depth 1/16".
If tires have visible damages they have to be replaced immediately.

If you have an accident and your tires are just close to that limit but still ok it may be that the insurance will not pay all because the accident might not have happened with better tires.

Tread depth here is 1.6 mm. It must be a minimum of 1.6 mm over the complete width and entire circumference. Age doesn't matter unless you have an accident - then your insurance company can get funny.
There was a report on the news this week about a coach crash that killed an 18 year old boy. The tyre that blew and caused the crash was older than the lad. It led to a recommendation that coach tyres, fitted to a steering axle, are no older than 10 years. But it is only a recommendation!

Will test to see if 50-55 psi works but not willing to go higher. If difference is negligible I will drop back to 45 cold. Will take time to test as I'm just getting a zero...first tank with new tires on the car. I use car computer to get a average of trip to from work. Minimize variables by taking same route. Wind rain ect. Out of my control but gives a good base read. Then will pump up a bit more. Granted I'm wary of anything over 50. Will have to test but roads I drive are a bit rough so Guessing 50 would be the high without additional discomfort in ride. Roughly 45 cold ATM recheck just the other day. Ride is very comfortable and quieter than the bald fuel max tires. Didn't lose my mind from road noise then so not severely concerned. If I can get 2% more fe from 5 psi I'll do it. Need to put American made back in top 10.

Current tank looking to finish around 54+ mpg. Little low ATM from pissroding it to test new tires lol. 46 mpg for first 130 miles. Just shy of 51 now at 212 miles.

Am I right in thinking the Chevrolet Cruze uses the Family 1 engine that Opel/Vauxhall developed?

All I have really found when looking for specs on the tiny motor is that it's family O. Is O for Opel? I don't have your guys intense digging capability. Half of you active members can name all the parts on your cars...that you didn't create yourself lol.
Anyways I'm curious how 90 day average works on here. Last 3 tanks fall into 90 day the one prior is 3/28 and clearly still in the calculation. 7/6 today(101 days counting fill day I think) just curious if calculation is automatic or someone does the updating. I should be in top 10 yet with 54.4 mpg. Happy with my numbers but I like being in top 10 since I have only been doing this for a few months lol must thank Xtreme from over on Cruze talk for directing me to this page.

It appears you have to add a fuel log for it to update.... maybe you can edit and then it may update as well? I know it's not automatic over time.
