Replacing run flat tire?
#16
The difference is noticeable once you get them. A lot of the sounds I attributed to road noise were actually caused by the wheels. Depending on the tires you get you'll get a much more comfortable and quiet ride. My only struggle was finding aftermarket TPMS sensors. Had to by OEM ones. The thread I started "TPMS registration woes" has more details.

Problem is, on a long trip one would likely need the trunk space for luggages and such. You carry a spare tire in the trunk? Have you actually done this or this is your plan?

This forum's software auto sizes uploads which is a nice touch really.
Most forums have a maximum file size upload of less then like 150kb so you have to keep shrinking until they fit. Now that is a PITA!

I finally figured out how to post the photos (3). The tire is a 165/90 18 mounted on a steel wheel that has been cut down on the back side in width to accept the 165, the holes have the ball seat to accept the lug bolt. I carry items as pictured, two 14.5X1.5 alignment pins, slip joint and needle nose pliers that are in the bag with a tire plug kit also a 12 volt air compressor. I had all of this "stuff" from our last 2 or 3 cars except the alignment pins (which are a must have). The jack is from a 2019 Mazda CX9. The lug bolts on the NX are factory torqued to 95lbs which is a lot, most cars, trucks, suvs etc. torque to 85lbs. Although the "Modern Spare" has a nice wheel the tire is a 155/90 18 which is OK I guess. I would question if the supplied lug wrench can break loose a 95lb lug bolt without bending, it took all I had to break one loose with the 18" 1/2" drive breaker bar when I had the run flats. I had the tire shop torque the lug bolts to 90lbs when I put the 245s on. I carry the tire as pictured and the other items below. The 165 is 1/10 larger in diameter than the 245. as you can see it doesn't take up a lot of room in the rear, 29.7" in diameter.

This is true, the key word is "may". The rear full of luggage, cooler and other stuff can also be a hazard. No spare is is not a great idea ether (IMHO). I'll probably tie it down with a piece of rope to the top brackets at the left and right sides behind the rear seats. There is no good way to secure it to the cargo deck.

the cargo hooks will not support the tire/tie downs. They will break loose. They are not welded to the body. They are attached with a thin pin/rod. Do not trust them.

Having said that, I also thought about the fact that I never secure luggage, groceries, coolers, or anything else when I put it in the back. So what makes carrying the spare back there any different that one should secure it to the vehicle?
Just saying.....
