Question about tires and rims. by dandrews1

I've got the LR3 HSE with 19" rims.
 
What rules do I need to follow to get something like a 16 or 17" steel rim with offroad or winter tires.
 
I don't have the exact spec of the tire sizes with me, but just at a guess - 235/50/R19 would read to me like 235mm wide, side profile is 50% of that, rims size is 19" - so the total diameter would be 19" plus 117.5mm (4.6")for a grand total of 23.6 inches?
 
If I wanted a 17" rim, I would need a side profile of 6.6 inches... or for a 16" rim, a side profile of 7.6 inches?
 
I understand that I need to try and maintain the same outside diameter to keep the speedo and odometer accurate. not sure if a different tire will affect the traction systems / ABS / etc?
 
I could just buy 19" off road tires, but I didn't want to switch tires on and off of the original rims all the time, and wanted to keep the winter/offroad tires on their own rims. If I'm buying new rims, buying a smaller rim and tire is cheaper than buying rubber alone for a 19" tire.
 
Also, you can't deflate a 19" tire very much for offroading... with a 16 or 17" with a wide side profile, I can deflate them lots and get lots of extra grip.
 
Can someone recommend a good tire solution for this?
 
Thanks in advance!

You have a slight error:
235/50/19 would be 2 times 50 percent times 235 plus 19
this equals 235 mm + 19 inches = 9.25 in + 19 in = 28.25 in
That's too small.
 
Factory tire is 255/55/19 = 1.1 times 255 + 19
which is 280.5mm + 19 in = 11.04 in + 19 = 30.04 in
 
You are limited to a minimum wheel size because of your brake rotors. I don't know what the limit is but it may be only 18 inches for an HSE or may be 19. That is the main reason I bought an SE and not an HSE. I don't know if the SE can use 17 inch wheels but I think it can't. You can be pretty certain though that you can't run 16 or 17 inchers on your HSE.

LR3s in Europe are avaliable with 17 inch alloy wheels. So you good potentialy get a 17 inch wheel and tire combo. You would have a hard time finding a 17 inch wheel with the correct aspect ratio and offset though.
 
You could import a set of 17 inch wheels from europe...
 
Would probably cost a lot of money though.

RIGHT! I forgot about the OTHER side of the tire...
 
In either case, it looks like I'm going to have to get dirty to measure the size of the rotor this weekend and see what clearances I have.
 
Followed the link by british_rover and the UK site has some weird acronyms that I'm not familiar with...
 
for the HSE, the rims are stated as:
"5 alloy wheels 19 inch ilo 18 inch style 2"
 
I would assume that "ilo" is "in lieu of"?
 
Does anyone know if there is a recommended minimum safe clearance between rotors and rims?
 
Thanks!

Just throwing out some tires I have found online:
 
BFGoodrich All Terrain T/A KO (LT285/70R17 121Q)
 
BFGoodrich Krawler T/A KX (37X12.5R17 116)
<Side note: how am I supposed to read that tire size?>
 
They both have an "R17" at the end, which tells me they should work on a 17" rim - the KX also comes in a 20" size, but the sidewall is too tall.
 
Also found a Pirelli Scorpion ATR (265/70R17)
 
The outside diameter of these would be 31.6" - compared to the stock 19" rims with tire OD of 30.04
 
Would that be close enough?

37X12.5R17
 
Means a tire with an unladen height of 37 inches and an unladen tread width of 12.5 inches. It is a Flotation tire measurment and is what was used for tires back before the P-Metric measuremnt system was invented.
 
That tire is way too large for the LR3.

2005 LR3 tire update by nesuv

For anyone looking to replace tires, here's my experience. I now have 20,000 miles on my 2005 LR3 and I knew the Goodyear Wranglers were noisy, but it wasn't as huge a concern for me as it was my wife. (After all, I grew up driving pick-ups with loud mudders.) After reading the posts I decided to take the plunge for new tires. When I inspected the Goodyears on the vehicle, sure enough, they were pretty worn. The thing that amazed me was that the tires were actually cupped. I did not expect to see this. I shopped around for Michelin Synchrone and was able to negotiate $237/tire (list around$300). After having them put on, I can't believe the difference! They are virtually silent and you can detect an obvious increase in grip. Although Michelin Synchrones are a bit pricey, I truly believe you get what you pay for. This was definitely worth it and I now have the confidence to drive in the snow this winter!

The Synchrones are a much much better tire and is the OEM tire on the Range Rover now instead of goodyears.
 
I have no idea why rover does not put synchrones on the LR3 as well.
