Here I thought is was short for ruh-roh Shaggy.
So if I wanted to install a high mileage rated low rolling resistance year-round tire with white letters on the passenger forward of my Mazda SUV with a hybrid power train I should ask for a CX-50H LRR UTQG800 A/S RWL RF tire?
And please reset the TPMS…
Anytime I’ve seen R and R on an invoice it meant remove and replace.
I believe that is called a polysemous acronym…
You have to look at the context it is being used in… Have you every looked at your courtesy check or inspection sheet? Most of the time they have your tread depths and or brake pad/shoe remaining thickness, they are beside the LF, RF, RR, LR
Here is Firestones, the tires are spelt out, but the brakes are acronyms…
Here is a random one pulled off the net, it’s tires are in acronyms…
Yeah acura does that. Then Steph comes and explains it to me. I get all greens but I did get a yellow to change the brake fluid. An hour more and $100 and all was fine.
Hope I didn’t get off topic. I actually don’t know which topic this was from. Just in case, every time I get in the car and start it, I check the fuel level and the tpms. Caught a nail in the tire once before the wife was heading out of state. Saves the knees.
I’m not a big fan of RWL tires, fwiw
They look good initially, but will look rather faded after not too long, imo
Just the names of the second-to-last set of tires on my car was almost that long:
Pirelli Cinturato P7 All Season Plus II
RWL “Run while low(pressure)”?
From your Thread you started…
But to save you time…
RWL = raised white letters (solid)
OWL = outline white letters
WSW = white sidewall
BSW = black sidewall
As a Tire Whisperer, I am surprised you don’t know this, it has been mentioned more than once on here…
Thank you for that breakdown of tire graphics, appreciated.
Now I’ll be straight up front with all of you:
I’ve had life-long learning difficulties that make it hard for me to remember or understand which acronyms mean what, in any context, automotive or otherwise.
What concepts you may grasp after it being explained to you once, or maybe twice, may not get through to me after 4 or 5 times being explained, if at all.
And it’s not about me not “paying attention” or not “focusing”. I’m in the same classroom you all are in, looking at the same board, listening to the same teacher next to it. It’s just that what that teacher says doesn’t get into my brain, after 5 times, the way it does for you once or twice.
I’ve genuinely been like this all my life, and it’s severely stunted my ability to grow in my jobs, and stunted my earning ability accordingly. And the ones in the room, or at work, who did grasp things quickly would cover their mouth and whisper to each other and point at me.
I’m not looking for anyone’s pitty, I’m just looking for understanding.
The same way “Oh, my car’s gas mileage is in the toilet” - Well sir your eng air-filter is clogged with dust and mouse feces, and your tires are all 5-10psi under aired.
RWLs or OWLs look great again with Westley’s Bleach Right whitewall cleaner.
I have not had a can of that stuff around for over 40 years! Used it on my whitewalls.
Only takes a bit of scrubbing to get the white letters white again. When I switched to Michelins on my truck, no white letters, OWL, , I kind of miss them.
I think you are joking. When I buy new tires I erase arch the tires that meet my requirements, then print out the tire I want. Take the printout to the tire dealer.
Yes, that too. In the 60s at the service station we charged according to a flat rate manual, it used R&R as remove and replace.
And I learned a new term today: polysemous acronym.
R&R is still different than RR, but I get your point… 
Yes, I was.
Let’s not forget R&R is different than R&I when looking in a labor guide.
R&I an engine is remove and install. For instance, if you have to remove the engine from a car so the body shop can do a frame repair. You just take it out and put it back in.
R&R is remove and replace. For instance, you’re removing an engine and replacing it with another one. You may have to swap manifolds, hoses, accessories like alternator and water pump, drain the oil, etc.
You know what I’m talking about…
