I'd like to mount some more aggresive tires in my 2000 Grand Nomade, I've been reading about Firestone Destination tires, right now I've got some Yokohama's tires. My question is: my tires say P235/60R16 but in Bridgestone site I found out that the closest are P235/70R16 ¿Would it be a problem? ¿Would those tires bump?
Grand Nomade,thats a grand vitara right?235/70/16 may rub it depends on the tire ,the tire of choice for a more agrresive look(A/T) and a stock suspension would be the 225/70/16.This is what i am running in an A/T ,looks good.
Thx for your quick replay Natlos...I think I'll try to get some tires that match those I have now....And yes, It's a Grand Vitara, the difference is that here in Chile it has 5 doors instead of 3...
The only thing to be cautious of is damage to the transfer case when increasing the aspect ratio (235/70R16) of the OE tire size. In other words, a 235/70R16 may give more A/T tread patterns to choose from, but it is a good bit taller than the original 235/60R16. It is possible that the transfer case could be damaged if you increase the tire diameter by more than 3%. Do the calculations and see if the difference is more than 3%.
I agree with the Bull. The time this will happen is when you mix different sizes on the wheels - so long as all tyres are the same size and aspect, no problem.
The main thing to worry about for me is the difference in speedo readings - it is too easy here in the UK to get speeding tickets as it is without having an unreliable speedo reading. There are plenty of tyre comparison site on the web that allows you to check the differences in speedo readings - A wider section with a lower ratio - or a narrower section with a higher ratio may be the answer - I went with the 225/70 without any problems.
Let me clarify my transfer case statement....there is more of a chance of damage to the transmission with a bigger aspect ratio over the long term of such tires being on the car. This can occur because the transmission is set up for the OE tire diameter and increasing the overall tire diameter will not only give a false speed indication, it can also lead to transmission failure.
If you use a wider tire, decrease the aspect ratio....but like I said before you will find it harder to find an AT tire with lower aspect ratio.
I've seen this damage happen many times, so just be careful. The transfer case damage can occur if any of the four tires tread depth is drastically different than 2 or 3 of the other tires on the car. It is recommended by more tire manufactures and vehicle manufactures to replace tires on 4wd cars with 4 of the same type, depth and size.
I agree with you netlos . I`ve been running 225/75 /16 since 2002 on my GV without any problems. I`m about 4 kicks off on the speedo but other than that it`s all good.

Your comment about being off by 4 ticks is exactly evidence for my point. The transmission is set up to expect a certain diameter tire. When you change that diameter, you are sending a different revolution to the transmission and can lead to long term problems with the transmission. Try to get waranty repairs to a failing tranny when the tires are larger than OE, and you will be paying for the repairs yourself.
If you do change tire size, I recommend to have the transmission adjusted accordingly.
