• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Tire size comparison

215/60-R15 is also a right size. I have one Michelin HydroEdge already install and the speedometer is now the same reading as the GPS.
 
Last year, I found 2 Michelin in 165-65/R14 from a web site in the US. It's now unavailable this year. (???)

In Europe, they have 165-65/R15 available but not here in Canada.

For those who really like the HydroEdge, Simpletire.com still has a few in stock.
 
From an earlier post - still applicable -

In the stock 225/50R15 rear tire size there are limited options, this is why many have tried other sizes to open up the options of what is available. As a side benefit, the speedo becomes more accurate.

In regards to this, here are some of the other sizes and how they differ in diameter. The first number (225, 215, 205) is the tire width in mm, so going to a 215 instead of a 225 width you are going 10mm narrower (which is 0.39"). Going to a 205 is 20mm narrower (0.79").

Diameter is not as clear cut. The stock 225/50R15 tire is 23.86" in diameter (or 606mm). When you go to a 215/60R15 it is 25.16" (639mm) in diameter, or +5.4% larger. Another popular size with many options is 205/60R15 and this one is even closer in diameter to the stock tire at 24.69" diameter (627mm) which is only +3.5%, but is slightly narrower in width. Both of these sizes have been used by forum members with good success. The nanny does not care about this size difference.

There are some other sizes, but very few tires are available in these. Like 215/55R15 (+1.9%) or 205/55R15 (+0.1%) sizes, they are closer in diameter to the stock tire than the 60s. There’s also 225/55R15 but this too is tough to find, that one is +3.7% in diameter.

Here is a great link to a tire size calculator I use to figure all of this out - http://www.tacomaworld.com/forum/tirecalc.php
