I had a feeling they would be even narrower. I need to measure my spare and see how tall it is. I know that it does fit in the factory spare location though. Regardless I think the tall skinny mickey thompsons are great. I saw a set on a 4th gen Taco awhile back on factory wheels and they looked awesome.I just measured my spare and I’m seeing exactly 8.625” tread block width and about 34.75” tall.
