Tire info by my_mr2

I have a 2005 Highlander 2WD with the 225/70 -16, and use snow tire in the winter.
  
I needed fair weather tires, for Hwy use only with fuel mileage, comfort, and noise as the priority. I ended up with the Kumo Solus KR21.
 
I like the price (under $120 installed for each tire), the warranty (80,000 miles with road hazard), and the noise levels. Oh and they are way better that the O.E. tires.
  
Thanks,
Mike

I just bought new tires for my 2006 Highlander and the tire store suggested putting 235 tires instead of the 225. Does this make a difference? My Toyo seems to drive very different with no play whatsoever in steering.

I am not sure what affect this may have on your Toyo. Larger tires may change speedometer reading to be off just a little. I live in Montana where we drive in a lot of snow and ice in the winter and I have noticed ice and snow build up between the rear tires and springs. Larger tires would mean less clearance but probably not be a big deal. I think larger tires cause speedometers to read slower mph. I noticed a 5 mph difference on a truck I put larger tires on. I was going 55 on speedometer but 60 actual speed. Yours might read 2 to 3 mph off. Someone out there might have exact difference. Not an expert on this for sure!! If it drives and handles well, you made a good decision to go with larger tires. Only time and Toyota will tell you if larger tires will affect drive train, transmission, AWD, etc.

the difference in this case is very, very small. the 235 tires will be a bit wider (10mm, to be precise). The issue to be concerned about is that as the width changes, the height of the tire (sidewall) changes too, even tho the # after the 235/ will be the same.
 
That number (the xx in 235/xx) is really a RATIO, not an exact dimension. So as the width gets wider, the sideway get taller if the same # or ratio is used. Therefore a 235/40 is a bit wider AND taller than a 225/40 even tho they are both /40. ( i use /40 as an example; I don't know what the # is on your highlander)
 
It's the change in sidewall height that can cause the issues with speedometer accuracy.
 
However, in this case the difference is so small that you really won't notice any change at all. A change of up or down 10mm is almost always of no concern.
 
If you want to play around a bit, tires.com has a calculator to see what happens as you change tire sizes. It even shows you how much your speedometer will be off.
try it here: http://www.discounttire.com/dtcs/infoTireMath.dos
 
years ago I moved my camry from 195 all the way to 225 (a 30mm increase!), and in doing so also changed the sidewall # so as to keep the sidewall height the same and avoid any speedometer issues.
 
The advantages of wider tires are better traction in all conditions (simply more rubber on the road). The downside is that more rubber on the road can hurt gas mileage (higher rolling resistance). The other issues about wear and tear and torque and all that are largely inconsequential considering all the real factors that apply. I have had the +30mm tires on my camry for over 200,000 miles (not the same set mind you!) with no problems whatsoever.

Well, if you live in snow country (like Montana), you may find that a skinnier tire digs through the snow down to the pavement better. More rubber from a wider tire can cause you to float over the snow and lose traction.

Thanks Kenlw !! I knew there was someone out there that is far more knowledgeable about this subject than me. That is what is great about this forum. I did not clarify, and should have, that the tire size change on my truck was significant. Completely different rims and tires. I apologize for that boo boo.
 
Appreciate Kenlw responding and pointing out that there is not much difference in these tires affect on the mph and vehicle in general. I will be more careful in future posts.

Yes, steve, the larger footprint of a wider tire DOES reduce the pressure (caused by the weight of the vehicle) since it is spread over a larger area (footprint). The change in this case would be about 4 sq in of contact area assuming a 12" long footprint.
 
But the tread pattern will negate this in the case of liquids like water. Which for us here is a bit more common than snow...... and beach sand is a solid that we would really not dig down thru!

Update on Kumo Solus KR21 tires in the 225/70/16... Have over 500 miles on them now, and wife drove in black ice condition in the Milwaukee area yesterday. We a 2005 2wd V6 HL.
 
Very nice tire for noise, hwy comfort, and fuel mileage. They also preformed well in black ice conditions. Wife commented about slight slip on take off in traffic, but would grab in 1/2 rotation with traction control, while others in traffic could not get move and would start going sideways. Stopping and turning was not an issue.
 
Vary Happy with selection... Did I mention they are only $120 each installed.

Very nice tire for noise level, good hwy comfort, good fuel mileage, and very good in bad weather conditions. We also like the free road hazard that Kumo gives.
  
Vary Happy with selection... All for under $480 out the door.

Replacement tires for 08 Highlander by btac
Jan 03, 2009 (6:32 am)

I am trying to get replacement tires online for my 08 Highlander and everywhere I look, they don't have the P245/55R19?
 
Does anyone know why it is so hard to find? I have 20k miles on the original Toyos and while I love the car, I'm not impressed with the tire tread.
