Shouldnt affect speedo,it just means 235mm wide tyre,instead of 225mm.its the 50 thats long as the ROLLING RADIUS is the same..JUST beaware,that that much rubber on the road for a small vehicle,will reduce the pounds per square inch weight on the road,thus making it more likely youll slide off the road first Holden Adventra 4x4 has only got 225/60/17s,and that weighs 2 tons

    Your rolling radius will change even if you keep the ratio at 50 the same. The ratio is between the tire width and height, thus changing the width will also change the side wall height. 50 ratio means that your side wall height is 50% of the width of your tire. Increasing the width of your tire does not mean you will go sliding off on your first corner. If so, why do sports cars come with wider tires when they weigh less than sedans?

2013 impala can i put 18 inch 235/45 on my 2013 impala

If the wheel size is, say 235/ 70/15, then yes as long as it fits. 235 is the circumference of the tire and it won't change your speedometer reading.

I have a 2007 Chevrolet equinox it has 235/65-16 tires on it can I put 235/75-16 on it without affecting the computer components in the car

Any change in tire size from the factory installed tire size will affect the systems on the vehicle. Your speedometer will not be accurate, and in your case your will be going faster than what is stated on the speedometer with a bigger tire. It will also effect your ABS system if your vehicle is equipped, but only a small amount and some ABS systems can be relearned with a different tire size by a scan tool (but it will not fix your speedo). One option you may do is contact your GM deler and see what it would cost to have a PCM and ABS program intalled, GM offers reflashes of the modules to compensate for aftermarket equipment, but GM charges the dealer for this service, and will of course pass the cost down to you.

Recommended tire size is 2352/70/R15 can I change sizes?

I don't believe there would be a problem due to fit but this is difference in measurements.
The 75 diameter (across tire) is 28.88 in.
The 70 diameter is 27.95 in
The 75 width of tire is 9.25
The 70 width is also 9.25
The 75 circumference 90.72
The 70 circumference 87.82
The 75 sidewall height 6.94
The 70 sidewall height 6.48
The 75 revolution per mile 698
The 70 revolution per mile 721
The 75 speed at 50 and the 70 is 48.4
I can't see why it would not work.

I have a Chevy Equinox LT with 235 60 17 tires on it.. I came across a set of 235 65 17 tires.. Can I put these on or would they affect the car/performance?

They would be fine, they will be a little bit taller then your factory tires, but you should have plenty of clearance on that model. May effect your speedometer, so pay attention to speed after changing to different tire size. Should only be a half inch difference I think, so your only talking a couple miles an hour. Easy test put cruise on 60 mph. drive 1 mile timing it should take exactly 60 seconds to reach the end of the mile.

I recently purchased a 2007 Ford Sport Trac Limited. I just realized that the 4 new tires installed by the dealership prior to my purchase are 235/60/18 but the recommended size is 235/65/18. Is this...

5mm is NOTHING to worry about,these are more expensive than 235/65/18,it means that they are thinner (closer to the ground) they MAY effect you speedo very slightly.but you will feel more secure.less sideways movement... geoff

My speedodemeter is off by 8 miles an hour could that be fix just by changeing out my transmission because the transmission doesn't shift right it takes a min.

Assuming you replace it with the same transmission it should be fine. If you've changed your tires to a larger or smaller size it can also effect your speedometer. If this is the case it can usually be corrected by replacing the speedometer cable with one for that particular combination. If your transmission isn't shifting right you should check the fluid level. Also check for any transmission leaks because those can effect the shifting as well.

Is it ok to go from 235 70 r15 tires to 235 75 r15 on a 1999 gmc jimmy

Yes its ok, the 75 tires are a little taller. your speedometer will not read correct speed, you will actually be going faster than what it reads.

Change tire sizes from 265/40 to 265/35 and 225/40 to 225/35

When resizing tires, the best method is +1,-1 or -1, +1. That is, if you add to the width one size (i.e. 235 -> 245), then you need to go down one aspect ratio (i.e. 40 -> 35). So if you run 225/40ZR18 tires and want to keep your speedo accurate, 235/35ZR18 works for a "plus one" and 215/45ZR18 will work for a "minus one" change. This way, your impact on speedometer accuracy is minimal.

Hope this helps,

Have changed tire size from 15 31 10.5 to 15 235 and have a 7mph error on speedometer

You are wanting to correct the speedo?

the toyota dealer should be able to reflash the computer for your tire size and this will correct the speedo
or you can buy a programmer like a hypertech or superchips most of the power programmers give you option for tires
